I can confirm that I am seeing the same issues in my unit. Connection Manager only offers View Advancement or View Profile options for all adults that I checked. I have verified the ones that I checked are on our my.scouting roster in their registered roles with matching BSA IDs.
I replicated the issue in Firefox and Chrome, both in regular windows and in incognito/private browsing windows, with and without any extensions (including Feature Assistant) running.
I confirmed that I can set other permission toggles when inviting an unconnected registered leader to connect from Scout’s Connections → Add. This works on all browser/window type connections I tried (with and without the Feature Assistant running).
ETA: I also tried toggling my Unit Admin role to make sure that hadn’t glitched behind the scenes. No change in behavior.
