I hope I can explain this correctly as its a hard one to track down. I can repeat it at will now though.
I have an existing map working for months then a quirk. I am using a simple Arcade expression in the Pop-up Title field (expression/expr0 with a calc of
Concatenate($feature.PlotID, "_", text($feature.FieldEvalDate, "Y-MM-DD")) so nothing fancy.
This Pop-up Title is on a related FC. When I go to the parent and list the children it works fine with 1 record.
But if I have 3 children the list will not show the Pop-up Title. (note sometimes it displays online but when I go offline it stops working)
And then the entire popup also breaks. Just spins.
Once this happens Field Maps starts going down in flames.
The map just spins
Then basemap goes away.
It says it has offline areas but none found.
And even the log files breaks. Just blank screen.
Only way to come back from this is the close the app completely.
It seems to me to be some type of memory issue.
If I change Pop-up title to just be a field everything starts working again just fine.
So it only happens if the Pop-up Title is Arcade and there are 3 or more children. The pop up has other Arcade it but does not seem to matter. Just the title.
I have this in a test set so I can share to the team if you want. Again I can break in a repeatable fashion.
Thanks
I am having a very similar issue to this on enterprise 11.1. @DougBrowning has this issue popped its head back up?
