Glad to hear it. I saw your OP back in November when this happened to me, and have been struggling along on my iPhone with FMG15 for months. Today for some reason, I was in the App Store and noticed there was a list of all apps I’ve ever bought. I checked the Claris website and saw that FM Go 15 is supported on my iPad, and on any iOS over 9. Well, then it dawned on me... maybe delete-reinstall. Poof, like magic. It worked. After I was done I remembered this post, and thought I’d pass along the solution for other poor souls still using 15. Glad it helped!
