Thanks for the insight.
We have reproduced this with multiple users, both are level 2 users: one admin, one data editor.
We've also tried this on devices what only have Beta installed and devices with both apps installed so it doesn't seem to be any app conflict.
Tomorrow we're going to see if we can actually collect in Beta while connected. We've only tested Beta offline because that is our #1 business use case.
Does the app have any internal logging we can check?
I'd be posting this on the beta forums but that place is like tumbleweeds blowing by.
Thanks for your help!!
