Practitioners reported broken pixel data, 0% Advanced Matching activity, and missing event parameters on April 15 — while Meta's official status page stayed green the entire time.
Quick summary
- Incident date: April 15, 2026
- First reported: ~12:49 PM ET (via @herrmanndigital on X)
- Services affected: Meta Pixel, Events Manager, Advanced Matching
- Severity: Silent — 0% Advanced Matching activity, no event parameters detected
- Official Meta status: No acknowledgment — status page showed green
- Resolution: Ongoing as of time of writing
What happened
Around midday on April 15, 2026, digital marketing practitioners started reporting a specific pattern in Meta Events Manager: pixels showing as Active with high quality scores (9.0/10), but with Advanced Matching completely broken.
The symptoms were unmistakable. Inside Events Manager, the Advanced Matching panel displayed: "0% of your Purchase events are receiving the following hashed customer information through your Advanced Matching setup" — covering all fields: city, email, first name, last name, phone, state, ZIP, and country.
Simultaneously, the parameters panel showed "No event parameters were detected" and the main activity view read "No activity was received in the selected time frame" — even for pixels that had received signals within the last hour.

"the accounts with problems are seeing this"
Posted at 12:49 PM ET on April 15, 2026, alongside a screenshot showing 0% Advanced Matching activity and no event parameters detected — despite the pixel showing Active status and a 9.0/10 quality score.
Why "Active" pixel status is misleading
The dangerous part of this incident is the disconnect between what Events Manager shows and what's actually happening. A pixel can show:
Active status
The pixel is firing and Meta is receiving signals. Technically true — but it says nothing about whether the data attached to those signals (hashed emails, phone numbers, etc.) is making it through correctly.
9.0/10 quality score
Quality score reflects the structural completeness of your pixel setup — not whether Advanced Matching data is flowing in real time. A high score during an outage is a false comfort.
0% Advanced Matching
This is what actually matters for bidding and ROAS. If hashed customer signals aren't reaching Meta's matching infrastructure, your campaigns are bidding blind — no lookalikes, degraded retargeting, broken conversion attribution.
The business impact: Advanced Matching typically improves conversion attribution by 10–20%. When it drops to 0%, you lose that match lift — campaigns that looked profitable may be bidding on far fewer matched users than normal, quietly degrading ROAS without any visible error.
"Same sh*t, different day" — the April pattern
The r/FacebookAds community titled their April 15 thread "Meta Ads 04/15 — Same Sh*t, Different Day." That framing isn't hyperbole. Foxwell Digital's community bug tracker — which logs practitioner-confirmed Meta issues in near real time — shows a dense streak of Ads Manager failures in the days before this incident:
| Date | Issue | Status |
|---|---|---|
| April 12 | Required field with zero selectable options blocking ad set publishing | Fixed ~30 min |
| April 13 | Creative Hub mockups invisible in Ads Manager ("No mockups available") | Workaround only |
| April 13 | Meta auto-enabling ad enhancements, resetting learning phase and stripping social proof | Workaround only |
| April 15 | Pixel / Events Manager: 0% Advanced Matching, no event parameters | Ongoing |

The real problem: Meta's status page said nothing
While practitioners were posting screenshots of broken pixels, metastatus.com showed no known issues across all services. This isn't unusual — Meta's status page has a track record of being late or silent on issues that community monitoring catches in real time.
Why the gap exists
Meta's status page reflects internal monitoring thresholds — a degradation has to hit a certain error rate before it triggers an official incident. Issues affecting Advanced Matching data completeness (vs. raw pixel fires) may fall below those thresholds even when the business impact is material.
Community monitoring is faster
Practitioners like David Herrmann (47.6K followers) and platforms like Foxwell Digital's bug tracker consistently surface real-world impact faster than official channels. By the time Meta posts an incident, practitioners have already found workarounds — or the damage is already done.
What to check right now
- 1 Open Events Manager → Advanced Matching: Check your hit rate percentage. If it shows 0% or a sharp drop from your baseline, you're affected.
- 2 Check the Parameters tab: If it reads "No event parameters were detected," your event data isn't flowing through — even if the pixel fires look normal on the surface.
- 3 Run a Test Event: Use Events Manager → Test Events to fire a live event. If the parameters aren't showing there either, the issue is on Meta's infrastructure side, not your implementation.
- 4 Check your Conversions API (CAPI): If you have server-side events set up, verify those are still flowing independently. CAPI is more resilient to browser-side pixel issues.
- 5 Document the window: Screenshot your Events Manager with timestamps. If you file a support ticket later, you'll need dated evidence that the breakdown wasn't your implementation.
- 6 Consider pausing Advantage+ targeting: Advantage+ relies heavily on Advanced Matching to find high-value users. Running it during a 0% match period burns budget on lower-quality targeting.
