xfinity app not working

Installed the xfinity app (com.xfinity.digitalhome version 5.28.0-2) on my Android 14 phone and my Android 9 tablet.

On my tablet, app launches and presents a Sign In screen (which appears to be a native app). I click Sign In and it switches to another screen (not a native app; appears to just be a web browser) and reports I'm already signed in . I click Continue and it presents a DuckDuckGo search page (again not a native app, just a web page).

On my phone, the app just crashes continually; never even get to a sign in screen.

I've tried uninstall/reinstall, force stop, and clear cache/storage on both devices. No change. App simply does not work.

Does anyone test their software any more???

Update: Uninstalled the app downloaded from Google Play and installed the app downloaded from ApkMirror.com. Now the app works on my phone. Still does not work on my tablet. Oy!
