We’ve double-checked that the correct date range is selected and that no IPs are being blocked.
For context, this event was working properly until recently. We’re not sure if it’s related, but it seems to have stopped working since an update to our app that involved integrating Vite.js.
Another important point: we have other custom events (such as signup) that are still being reported correctly in Piwik.
Looks like something has broken around 11 May with tracking of that event. I see one one change 10th May that is unrelated, so could be that something was broken on your website.
Could you test that event again and check if console sends any errors?
