Thanks Raz0rEdge.
McBie - You may be missing something I think a lot of people do, and that is, when they see updates are available, they simply select "update all". I certainly did. And then I noticed one of my 'most used' apps decided they were changing their business model, whereby, what they once provided as part of the original purchase price, they now want a subscription for. I was not happy. So managed to revert to the previous release.
