I just started using Tracker with ArcGIS Enterprise 10.7.1 a few days ago. I am doing some testing on my Android Samsung S9 Note, Tracker Version 20.1.0 Build 2643 (always connected via wifi or cellular). I have yet to have the app upload data on it's own. I can successfully force an upload using the 'Upload now' process. I have had the app running in the background for 19 hrs. now with no upload. Any idea why this is happening? My colleague has been doing similar testing on his iPhone and his data has been uploading automatically as expected.
Thanks,
Matt
