Short form: it looks like that may be normal for connecting someone who already has a scoutbook account to a scout’s database record. i would need someone from SUAC to confirm, since i don;t have any spare adult accounts to play with.
ETA: Wait, there’s no link to accept the connection? Does the parent account show connected to the youth now, or is it still showing as pending?
ETA2: Has the parent tried logging into her Scoutbook account to check for a pending connection there? I’m wondering if there’s a new process that’s not documented yet.
