I am having the same issues since the update, and have done all the things told to try but still not helping, very frustrated. Today even try to uninstall/reinstall FTM 17 but then could not re-upload my tree until i had installed the undated it still did not help. I am using the Ancestry site but very its inconvenient when you have put so much time and work into your tree then have to deal with having to sort out problems.
Hope they sort it soon.
