I’m admittedly getting technical here.

If you're a Sapphire Reserve, J.P. Morgan Reserve or Ritz-Carlton cardmember and have not yet enrolled in your complimentary Priority Pass membership, you can activate your membership by signing in to your Chase account or calling the number on the back of your card.
I have done that.
Chase Sapphire Reserve, J.P. Morgan Reserve and The Ritz-CarltonTM Credit Card primary cardmembers and authorized users who have activated their complimentary Priority PassTM membership have lounge access.
By way of the simple
activation, it appears that you have access without actually having received your physical or digital card yet.
Should I bring my lawyer to the Sapphire lounge?
