I’m pleased to report that this feature now works for me. I was easily able to change and save my photo via either:
If anyone cares, here’s a screenshot of the success message. I pasted an old photo of me to confirm that it was different from my original.
Finally, I’m surprised that I can’t find this fix listed in May 20, 2025 Scoutbook Plus Updates - Scoutbook / Scoutbook - Scoutbook Plus Change Log - Scouting Forums. But that’s much less important than the feature working, eh? 
Thanks to whomever solved this issue.
