As of now the PWA is totally unusable compared to the Linux native app. Tried it in Chrome on Ubuntu 20.04 with Gnome Flashback/Compiz.
These are the most critical issues I see in the PWA:
- the sound is a disaster, speaker/headphone volume fluctuates between barely any sound at all to almost normal (same issue with microphone)
- meeting started notifications are missing
- have not found any way to autostart the PWA
Also the input/output sound device selections does not match what the OS displays and does not follow what is selected in OS. This goes also for the Linux native app where sometimes you have to change it when the app seems to forget last setting.
Then there are some other promised "capabilities" for the PWA that does not exist like custom backgrounds which is nice to have but not vital.
And the "make a test call" function is missing which is very useful when testing that sound and video works.
All in all, this is not a GA release, only some sort of BETA release. Until the most vital things are fixed, the PWA can not be used in a corporate environment and we have to stick to the native app where at least sound/video and notifications actually works even if some other neat features are missing.
