If there's something wrong with the game then this is the wrong platform to hope for a solution because the developers are not the involved in this site... As you said yourself it doesn't seem like a common problem, I am using VC on android 6.1 and still get notifications after months of playing.

I'm 100% positive it has nothing to do with the amount of cash you spent in the game or not though.

You could try some custom roms (e.g. cyanogen mod) on your old phone if you still have it.
