It's really annoying that for some people it says all the episodes are deleted because it's not true.

They're not deleted. That's an error message people get sometimes. Some solutions are to restart your phone, if that doesn't fix it, delete the ok. ru app & download the app again. Or if the app is giving you trouble, don't use it and just go directly to the ok. ru website. Let me know which of the solutions solved your problem.
