since yesterday i can’t login on my mobile phone (iPhone 6s, iOS 11) with my PTC account. Other PTC accounts can’t login as well. Error message is “authentification failed” (or similar, i’m playin in german language). The message appears already one second after pushing the login button.
I created a new account via gmail login, this works well on that phone.
The same accounts works on other phones without any trouble.
Niantic support writes that i should delete the app and re-install it and i should delete the browser cache of the safari. Both done without any change.
Does anybody have an idea what to do?
Thx a lot!
