I’m trying to get what type of device they are using and how frequently this is appearing. But thought I’d bring it up sooner than later in case others had experienced the same thing.
This has happened to me before too on some of my older apps that I used spaces/emojis in the Sign-In text! I just removed them and used special characters instead and all was well.
I checked the sign-in text and there was the default description of “Please sign in with your email”, which I’ve removed. The Greeting was empty. No emoji or special characters were used.
