When I tried to open QuickCapture on an iPad Mini (5th gen) version 14.7.1 this morning, it would hit the splash screen then close after a few seconds. There were no logs recorded as far as I could tell. I tried restarting the iPad to no avail. The iPad had been updated last week, and I do not believe I used QuickCapture between the system update and today. It was crashing before and after I applied the August 2021 update. I had made no changes to any QuickCapture projects.
To resolve I reinstalled QuickCapture.
edit: as AndrewDeLuca pointed out in a comment, this is not a permanent fix. I was able to use it for over an hour without issue, but it started crashing again.
I had a user express the same issue was happening to their Ipad Mini in almost the same exact scenario you described. I went through the typical troubleshooting process and found the re-install worked as you again described. However, after about 20 minutes of using the app in the field, my field worker said the issue was happening again. Again we reinstalled, and again 20 mins later she reported the problem. Has the re-install been a permanent solution for you so far?
I was able to take it out for 60 to 90 minutes yesterday without any problems. I probably never changed apps that entire time. Just for fun, I tried to launch the app again and… it crashed. So that was not a permanent solution for me either. I will have to wait until tomorrow to take a look at this or talk to esri.
The crash seems to be related to the external location providers. I have notified Esri with a more detailed reproduction; hopefully they can get a fix out soon. Thank you!
