Apparently it depends upon where you're coming from, and where you're going to.

Likely @Roger will answer soon enough to help you get where you're trying to go.

If the mean time, you may wish to start a support ticket at http://support-portal.plarium.com/ticketcreator/throne/en?devicelocale=en&spGame=throne-web  - from all accounts, what you are trying to do is certainly possible. They'll be able to help you through it. Seems that between Facebook, Google, and plarium.com , things get a little ... convoluted.

Hello aadesh!

To restore the existing account, make sure it was linked to one of the synchronization services in the Menu > Account. If the aforementioned account was not linked to the synchronization services, and you lost access to the previous device — please contact our Support Team regarding your issue (Menu > Ask a question). They will surely help you🙏

You can find the detailed information about account synchronization by the following link: http://support-portal.plarium.com/en/throne-web/faq/linking-and-restoring-your-account/description 

Have a great day!

Compete in exciting races in Kart Bros IO, where spee d alone isn’t enough—you must dodge attacks, grab boosts, and stay sharp to reach first place.

The battle method in Jacksmith is intel ligently designed, making every encounter feel strategic.

Linking your account to a synchronization service before switching devices is definitely important about Her Trees. This in formation will save a lot of players from accidentally losing their game progress. 

You may need to finish the tutorial first before the account switch option appears. After that, try logging out from Settings and sign back in with your existing account.

Had a similar issue before while switching devices. Much more frustrating than figuring out a conversor de letras.
