"there seems to have been an unexpected problem" ERROR
I just did a clean flash on my S8 with Android Pie and installed Swiftkey as usual. The only issue I encountered was signing in with my Google Account. It keeps looping between asking for Offline Access to my Google account, which I granted, and back to the sign-in screen again.
After multiple tries, it just tells me "there seems to have been an unexpected problem. Please try again later".
Have tried reinstalling the app too but to no avail. Kindly advise, thanks!
