This started happening a couple of weeks ago. I keep getting logged out of Collector repeatedly. Having to log on to Collector each time is annoying but did not cause a huge issue for me since I am setting up the map from a WiFi-enabled office. However, we had an offline field data collection project, and this issue cost us a lot because the field staff was logged out of Collector automatically while they are out in the field with no internet connection.
I would like to know if this is a bug and what is the workaround to avoid the automatic log-out.
