Multiple playlists deleted on iOS

I've slowly noticed that my playlists on iOS have been getting deleted, I'm on the latest iOS version and I'll test this in more scenarios to see why it happens when I have more time

I believe it's due to Safari's handling of old, unused local data. I'm redesigning the module that handles the IndexedDB to see if theres a better way of me handling it
