Deleted App by mistake in Admob

Hi,

By accident I have deleted an app in my admob app list and now when I re-add it I am getting a new Publisher ID. So all my active users don’t see the Admob ads anymore. Is there a way to revert it/manually change a Publisher ID of an app?

If I bring out a new update with a new ID it would take months for them to update it and I would lose 1.000ts of $ :frowning:

Thanks!
