I am a asst scoutmaster trying to approve items in IA it has me listed as a committee member
Internet Advancement looks to your registered positions and functional roles at my.scouting.
If you are supposed to be registered as an Assistant Scoutmaster, then you can ask the Chartered Org. Rep. (or COR Delegate) if they will use the Position Manager at my.scouting to change your position to ASM.
Alternatively, one of the troop’s Key 3 (Scoutmaster, Committee Chair, or Chartered Org. Rep.) or a Key 3 Delegate can use the Position Manager to give you the functional role of Unit Advancement Chair or Key 3 Delegate.
Edited to add: Please note that you will need to wait overnight after any changes are made with the Position Manager.
