There have been many businesses suffering with the we do not support your location bug hindering Google Maps businesses for a long time.
Google's Jade Wang said in a Google Business Help thread that they have fixed some of those who have issues with it. She wrote:
Good news -- we’ve been able to bring back some of the listings that incorrectly had the “We currently do not support this location” error. Many previously deleted service area businesses that had their addresses correctly hidden a few weeks ago are back.If your listing’s not back yet, please know that we are still working on it. In the meantime, please review the quality guidelines and this article about service are businesses. Make sure your listing complies.
I wonder if this is all fixed.
