Unfortunately as the issue is still being investigated, we do not have the answers you seek. We suspect the issue may have started with iOS 26. The root cause is not determined yet, but we believe there is a specific trigger for this issue to surface - that is, it does not effect all apps that get deleted and re-installed every time, all the time. All that will be part of the investigating and fixing process.
