Anyone with a virtual business manage to verify multiple GMB on one account?

My 2nd location isn't receiving the postcard. I'm wondering if Google has flagged my account or something. The location is a (virtual) office space that I rented - just like my 1st location.

I'm using multiple locations because all my top competitors do it and I know it benefits them. And they somehow managed to get their multiple locations verified. Of course the locations are hours apart though, as is mine.

Anyone with a web/seo business manage to get multiple locations verified through postcards?
