Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
When trying to advance one of our arrow of lights we are getting some errors in both scout book and in internet advancement. no one within our pack or council has transferred this scout. Screen shots below.
I did this, and can now approve and award his cub stuff in Scout Book, but the same message with the yellow Error icon is still showing in Internet Advancement.
He has an old Scoutbook membership that is not approved:
date started 2016-09-01 / date ended 2019-01-02
Try approving it, and see if that helps. You might need to temporarily end his current membership – but stay on his Membership page in Scoutbook while you approve the old one.
