Yes to all of the above.p4ran0id":w5ixoly3 said:Have you tried to un/reset Google play app? Also try to delete your Google account from smartphone and login again. That could help.
If none of these help, try to delete your Google account from device and create a new account, no need to buy the game again, just try if it possible to use cloud save with the free version.
As mentioned, I will use the ek.bak option from now on instead and back it up manually on google drive.
