So, iPhone event is now scheduled, 9/14. I've not gotten any response on this forum, or on the feedback report I've submitted, so it looks like my customers are all going to be dead in the water because of this. If anyone has any suggestions, I'd love to hear them.

@aliraza0801 I think you are describing a slightly different problem, but having said that, the problem I was experiencing appears to have been addressed in iOS 15.1 Beta 2, so I would download the latest beta and retest.

@samoilyk fixed in 15.1 beta 2, continues to function as expected in 15.1 beta 3

We are getting reports that this problem has cropped up again in ios17. We will do additional testing to confirm, but I fear that our customers are going to have a major interruption of service as a result of this.
