How to fix a disconnected location in my Google My Business account?
If a Google My Business (GMB) listing is disconnected, Birdeye will display an error message prompting you to connect your GMB listing. Once the listing has been connected, you can reconnect the GMB listing with your Birdeye account.
Delete
SOLUTION
Google starts 'un-verifying' the listings in which it does not notice any activity for at least 6 months. In this case, you will see a 'disconnected' status. To reconnect them again, you must delete these listings and get them 're-verified' by Google. To learn more about verifying your GMB listing, read the help center article: How do I verify my Google My Business listing?
