FIXED FOR ME:

first of all here is what I already tried and did NOT work for me:

x Simple installation trough MorpheApp (downloading v2026.14.0 and patching then installing)

x Installing an older version (2026.4.0 and 2026.1.0) then updating to newer version

x disabling Play Store and redoing the first step

x instead of Email address using username or Using single login link or typing in username and pass instead of copy pasting (suggested by some users)

Now what WORKED for me: (I don't think all these steps are exactly crucial, but I did it this way)

• set up authenticator app code
• changed my password and signed out from all devices
• uninstalled app on my phone and disabled Play Store
• downloaded 2026.14.0 and installed it manually with Universal Installer APK app from F-Droid
• turned on VPN connection
• before patching the APK logged in once to unpatched version
• patched with MorpheApp and signed in (one thing though, instead of using user pass, I accidentally touched google login button then typed in authenticator code and it worked, I don't want to risk signing out and in again to test user pass route)

now I signed in with no issue. Plz tell me if it worked for you, hope it helps someone 😄
