My only issue with Apple is now I have changed my location from UK to Canada, so can not update any of my Apps purchased in the UK without installing them on my devices or swapping back to the UK store. The free ones I had had to delete and re-download
I have an ongoing ticket that I wont let them close, I keep getting emails that say "are you happy with our solution" so they get a standard reply "no my issue is not resolved as you have not given me a solution".... been going on for a month now
