Microsoft Information Protection (MIP) Purview Labels show on Adobe reader by default upon install for Classification only labels.
When you are in Adobe Reader by default it does not show if there is a Sensitivity Label applied unless it has encryption. Would be good to have this on by default for all companies so when I share Confidential content they know this is labeled as such even though encryption is not there.
It seems the feature is there because I can make 2 Registry edits and it now shows there is a label and I get the option to change it.
PLEASE PLEASE PLEASE Upvote if you are in the same boat.
