Apple TV app verification failed error on Fire TV Cube 1st generation
I have a 1st generation Fire TV Cube and have been unable to sign into my Apple account on the Apple TV app. Both the Fire TV OS (6.2.7.3 NS6273/2773, with Fire TV Home Version 6240499.1) and the Apple TV app (version 4.1) have been updated the latest version. I've gone through various posts by users with a similar problem and tried reinstalling, the app and doing a factory reset. Nothing has worked so far.
I also have a Fire TV 4K stick running the same version of the Fire TV OS, and the Apple TV app works fine on that device.
If there are other fixes that I can try, can you please kindly pass this information to the software development team?
Thank you very much.
