I've always left Acorbat to it's own devices when it comes to automatic updates and generally they seem to happen in the background without user intervention or the need to elevate to an administrator. In order to update manually though, it appears you require admin rights. Do you know when or what triggers the automatic update? Is there a flag that Adobe sets to publish for manual update checks vs automatic? I haven't seen any machines move to v22.1.20085 as of yet.
