Found Solution to upgrade issue

At first I found like the rest of you the upgrade relocked my app purchase. After I went in to the settings on the top left (hold the gear a few seconds). There is a restore button in the middle that is available to click. Click this this will unlock everything again for you. I know this is a hard way to learn it but My daughter is now happy again at least. If this was not found I would have left my review as it was.
