I am experiencing this same issue. Member ID is: 141117347
I am cubmaster and trying to enter the adventure requirements “Bear Strong”
It is not started, i have tried in multiple different ways to update the adventure.
I have this occurring for several other scouts as well.
I have another ticket open already that could potentially be affecting this? Scoutbook Plus - A plethora of issues
however this is the first time i have personally run into issues entering advancement for a scout.
I am also glad to work with and do a screenshare if that would be helpful.
