Restore App Unlock

[Clashii 2]

Hello, 
i'm completely new to Emby, just installed my server yesterday and unlocked the App on my MiBox 2.Gen.

Everything smooth so far, but today i wanted to install the Emby App on my Chromecast on another TV, sadly i can't unlock the App there, as the "Restore Purchase" button only sends a "Unlock is not purchased" Pop-Up.

Am i doing something wrong, or is the unlock only for one device?

I am 100% sure i'm using the correct google account, as i'm able to see the unlock in my order history.

Thanks in advance for any help.

Double check that the new device is logged into the same Google account and also be sure the app was installed from the store (not sideloaded from an APK).

I removed all other accounts, and surely did load the app trough the App Store, still i can't restore the purchase.

I believe billing support has taken care of you.

Yes, thank you.
