When I make a Survey from an ArcGIS Server Feature Service (registered with ArcGIS Online) I run into the problem that my data is submitted correctly (I can see the new insert in the Geodatabase) but the Survey123 Field App gets hung up at "Sending Data". This problem only occurs when a repeat section is included (meaning a 1:m related table in the geodatabase).
Is this a known bug? Does anybody see the same problem? Does anybody know a likely cause or workaround?
I attached the log file in case that gives you any clues.
