A few of my end users are consistently seeing an error on their Collector applications. I've attached a screenshot. It states "Map List Error Unable to fetch list of maps.". In order to get rid of the error they must shut down the application and click back into it which ultimately solves the issue, until is occurs again the next day or sometimes hours later.
I can't pin down what's causing the error. I have the same version of the app (17.0.3) and iOS (11.1.1) that my end users have, but I'm not having the problem. These individuals have been using Collector daily for the past year and a half and haven't seen this error before which leads me to believe it's a new one.
Any ideas for what I should troubleshoot?
