Could you share more details on your app configuration? It's an attendance tracking app that uses mostly SQL tables and views as well as a sharepoint data source.
What controls are included in the app? Galleries, dropdowns,list boxes, checkboxes, date pickers, timers and buttons
Do only some of the users have the crash issue? We're unsure, users sometimes will encounter the crash and just accept the crash and reload the app without submitting a bug/crash report.
Are they in the same location? All users are within the same metro area in the US
When the app crashes on their side, do they get any returned error message? Not normally. Sometimes they'll recieve a 'Server error has occurred' when opening the app but they're still able to use the app.
