That’s a frustrating situation — account syncing issues like that are pretty common, especially when multiple login methods are involved.
In most cases with Plarium games, the key thing is to make sure the original account is actually logged in on mobile using the same method it was created with on PC. If the PC account was created via Plarium ID first and then linked to Google or Facebook, the mobile app sometimes won’t recognize it unless you log in using the Plarium ID directly. It can also help to fully log out, clear app data, and then try signing in again rather than using the reset option.
If that still doesn’t work, reaching out to Plarium support with your player ID is usually the fastest way to resolve it—they can manually check how the account is linked on their end.
Interestingly, this kind of issue comes up a lot across games and platforms, which is why having clear guides and centralized resources can be useful. I’ve seen similar step-by-step breakdowns for managing game data, scripts, and account behavior in places like this resource that focus on understanding how game systems handle connections and automation.
Hope you get it sorted soon — once it’s synced properly, switching between PC and mobile should be seamless.
