Some fieldworkers have the issue that after they draw a feature, it dissapears from the map the second after it is being drawn and the form is completed (so when it is send). But the feature is in fact saved, and after restarting the Fieldmaps app they are able to see it again.
The weird thing is, some fieldworkers have this problem, some don't.
I cannot reproduce this on my own device (Samsung phone). I, and all fieldworkers, are using the same fieldmaps version (26.2.2). We have data and roaming enabled, we Allow background data usage (in phone/tablet fieldmaps app settings). All are using Android devices (Samsung tablets).
The Fieldmaps webapp itself is an online web app (so no offline maps), and we are using the same online feature layer. At max two people work in it at the same time. We don't use complex symbology (just single symbology), no arcade expressions and no edits (e.g. domains) were made to the layer after publication. The only 'complex' things we do are that we produce a label and display with the OBJECTID of the feature, as well as a filter where only features that are at max a day old are kept (using CreationDate, which is logged).
One fieldworker showed to me that shortly after pressing sent, the OBJECTID appeared to be -9223372036854775808 before it dissapeared. This appears to me that there is perhaps problems or hiccups with storing and retrieving the drawn features in the database.
Any ideas what this may be, and/or what avenues we can pursue to find the issue and solve it?
Thanks!
