Red exclamation mark in App - Teams

(1) ShareShare
ReportReport
Posted on by 4
Hi,

I've added my app to Teams, but I’m noticing that a red exclamation mark appears at random moments.

I’ve already disabled background tasks (I had a timer set to auto-refresh), but that didn’t help. The mark still appears unpredictably, even if I’m not clicking anything in the app.

I’m logging errors using OnError, but nothing gets logged when the mark shows up. It doesn’t seem to affect the app's functionality - everything still works fine when the mark appears, but it’s a bit annoying.

Any insights or suggestions would be appreciated

    The icon shows up when this error appears in the console:
    Access to XMLHttpRequest at 'https://eu-mobile.events.data.microsoft.com/Collector/3.0?qsp=true&content-type=application%2Fbond-compact-binary&client-id=NO_AUTH&sdk-version=AWT-Web-JS-1.8.9&x-apikey=******' from origin 'https://apps.powerapps.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
    Server returning 503.
     
    Does anyone know how to fix this?
