Thor update v1.01 doesn't update on App Store
I purchased Thor for my iPad mini a few weeks ago and I love it. Anyway today when I checked my app updates it appears that there is an update to Thor to version 1.01. The odd thing is that there was no description of the update next to Thor and instead of the update button all I seen was the open button. Anyway I browsed Thor in the App search and indeed I seen the update button and selected it. It downloaded but when I opened Thor it turns out that it didn't even update as its still on v1.0 instead of the updated v1.01. Please help.
