I installed HS again after a while today, first on my iPhone, when trying to login (server europe) I saw a message similar to the attached screenshot.
The same problem happens when I try to login on my PC. Asia login works fine. However I do not have any cards(and payed content) there so this is kind of bad.
Errormessage on top right of the screen: “HS:NGRESULT DATA MIGRATION OR PLAYER ID ERROR_314:0”
The usual “Playful sprites” message is shown on the main screen, however restarting does not fix anything.
