Scheduling on iOS - Zoom saves appointments to the present time, ignoring the scheduled time.

[Retracer]

This behaviour first appeared in the last couple of days. I have many recurring meetings each week but their times vary. I regularly update the meeting schedule in advance with the new times. Now I cannot do this. When opening the schedule for a meeting, the time is set on the present minute. If I change the time to the correct time in the future, the saved meeting reverts to the present time. Sending the meeting to the recipient, the calendar link is also set to the present time, which is chaotic for my (and their) diary schedule. I have tried on two devices (iPhone and iPad) with the same issue. My partner’s iPhone can still schedule appointments normally, with the scheduler correctly recording the future appointment. 

I’ve tried rebooting the phone, checked my timezone, deleted and reinstalled the app… as the problem occurs on both my iPhone and iPad it seems to be an account issue? Any advice gratefully appreciated!
