I just had an update today, and this problem started. I tried resetting app settings, changing IP settings, uninstalling and reinstalling the affected apps. Everything short of a factory reset. On another fourm, someone said they bought a new wifi router, and that worked. I'm usually connected to my ISP modem but also have an eero wifi booster, so I connected to that. Wifi works on all apps now. This is obviously not ideal, and they need to fix whatever bug was in that update that is causing wifi to be blocked only on certain apps.
