Game either gets stuck on authorizing or skull-heart loading screen and either stays stuck or takes 20 - 40 minutes to load; have waited that long to test. And once it starts, usually keeps getting stuck on every skull-heart loading screen.
Pardon for the late response.
Device : mostly on samsung j7. Android 8.
Network type : switch between cellular network (lte) and wifi. Vpn and vps both with residential ip.
Ping was the same while game was having longer loading screens and was running normally.
Been encountering this long loading screens lot less for a few days.
I have the same issue now.
The only thing i did - changed language from Russian to English. I played for a while and now i can't even get my daily reward.
