So #duolingo now wont run on my #grapheneos phone, probably because it does some play integrity shenanegens that even the sandboxed google play cant do.
So I have to say goodbye to my 850 day streak....
@nprofile1q... For what it's worth, duolingo installs and runs just fine on iodéOS with microG, so it is unlikley that the issue is play integrity or a custom ROM. Try logging on to your account from the duolingo website, perhaps the problem isn't the device at all.
