Thanks for helping!

Thank you, Eric. That is somewhat helpful, but not an answer to this specific question/problem. My Air Tags are not visible via my Apple ID; only in the Items list in my old iPhone. So not on my MacBook Pro or my new iPhone, although I use the same Apple ID on all Apple devises.
