Hi @Anonymous ,
This is really weird. I just tried to do all the steps on the new instance of the portal and everything worked for me. Make sure that instrumentation key in the tracking snippet is the same as the instrumentation key for your Azure application insights resource. Actions on the portal might not be reflected immediately - there might be a delay of up to 5 mins. Please check if you can see events right now - maybe you just checked to early. Also, you can try to restart the portal - maybe it will help. To do so go to Maker Portal (make.powerapps.com), open Apps, find your portal app, press 3 dots and select Settings, there select Administration to open portal admin panel, there go to Portal Actions and press Restart.
