Soft suspension? How do you know?

[Scott ClientClicks]

I have a client with a SAB for a dog training business that they can no longer manage. They are certain that they are logged in to the correct google account. The listing doesn't appear to be suspended because I can pull it up in a search. But I'm wondering whether it might be soft suspended. How do you approach troubleshooting a SAB that can't be accessed? I suspect a soft suspension because they rebranded the business name and website over the past month. They changed the name in the GBP and have been accessing it fine for over a month, so I'm a little surprised that it might only now be affected.
