Thank you for that info, I really wasn’t sure which update had killed the functionality. I really hope this helps and that I can get it to someone in Apple who can get this resolved after a spent time beating my head against a brick wall with a first line support person who has to go through their cheat sheet of questions, then had the line ‘dropout’ when I was being passed to a senior advisor and have received no call since.
I will follow up today and, if luck is on my side, get to talk to someone who understands what I’m actually saying to them and can feedback to the right people to get this issue resolved in the next iOS release.
