Even with Google Play enabled, and the Assistant Android app installed through the Play store, I randomly get this error occasionally:
Something went wrong
Check that Google Play is enabled on your device and that you're using an up-to-date version before opening the app. If the problem persists try reinstalling the app.
Then after a close an re-open it works for me. Does the app really need to engage with Play Services at all? It would be better if it could be installed without any communication with Google at all, like through Aurora, F-Droid, Obtainium, etc.
