ll of the above options are not suitable. The problem is only with tracks that were previously found as Favorites, but open in different places. If I put a like on a PC, then it is not displayed in the android application, and if I press it again, it says that this track has already been selected as a favorite. I will help you check. Give me a technical task, and what should I do. Problem between platforms and imports.

I find the logic. If put a like on the first device, then it is not displayed on the other device. And on the second device, the like cannot be removed, a message appears that the track has already been added to your favorite. Tested between phone, TV and PC.
