Caldwell Ballistic Precision Chronograph App

I have a Caldwell Ballistic Chronograph that I have been using since 2020. I just went to connect it to the app and the app just opens and closes right away. Looking at the reviews on apple’s app store and it seem lots of people are having this problem. The last time I used it was back in July 2022 and today, no go. Has anyone else experienced this issue? I was going to reinstall the app and was met with the message that all my data will be deleted. At this point I chose not to delete it yet and to see if there is a chance it can be fixed.
