If the new address is located in a better place for rankings, then that's one reason to consider updating and re-verifying. For example, they used to have an address in an industrial area where there wasn't much search volume for their primary keywords, but the new address is in an a residential neighborhood where more of their customers are.
Otherwise, I might be inclined to leave it.
Yea that was my thinking as well but now I am dealing with a suspended listing and not really sure what the move is here. You use to be able to reverify an address when suspended (still need reinstatement) but now it doesn’t send a postcard. It seems like this reinstatement request is just stuck on nothing happening because GMB support has no idea what to do when there is any sort or abnormality :/
