I was camping this weekend and working POTA off and on as I had time. On Sunday afternoon I had 333 QSOs in my log. Later in the evening I re-opened HAMRS and I only had 183 QSOs in my log. Fortunately I was periodically exporting the ADI file as a backup so I did not lose data but the QSOs are gone from my HAMRS log. I ended up creating a new log to complete my trip and I experienced no other issues.
This was my first time using HAMRS and right now I am not sure I can trust using it again at this time.
I was using my 11" iPad Pro with iOS version 14.7.1 and HAMRS version 0.11.3.
