Content of iframe embed of In-meeting app turns grey
Hi, we have a working integration with MS Teams. We've built it upon In-meeting app experience. Some of our customers started to complain that shortly after the integration app starts to load, whole embed iframe becomes grey (HTML document is empty, console is clean). Their experience looks like this: Not much is going on there, right? 🙂 We've tried to investigate what's wrong, trying to debug it on our part. During the debug session with client, we were unable to open DevTools of this iframe (customer has Developer Preview with Upload of custom app turned on). Once the page turns grey, the whole debugger gets disconnected, so we were unable to continue with debug session. Version of Teams where this bug was reproduced: 1.5.00.8070 (32-bit) / 1.5.00.8773 (64-bit) both Windows. We also have customers on Mac reporting same behaviour. We think, that it might be issue https://github.com/electron/electron/issues/21834, but it is difficult to confirm. If you need any further info, please let me know. I will be glad to help. Thank you! Marek
