In my personal Bing account, I can import GMB listings, and as long as they were verified in Google, they were automatically verified in Bing, saving me an unnecessary step of re-verifying them on Bing.

Now I manage a Bing Agency account, and a Bing representative told me this option to import from GMB is only available for non-agency accounts.

She also told me "the option for import is new on Bing Places and due to technical challenges, Sync and Import with Google My Business feature is currently enabled only for users having maximum 10 businesses in their Google My Business account. Which is mostly applicable for small-medium business owners. Because normally agency accounts are being used to bulk manage multiple listings for different clients so while the option is still being enhance to cover more listings, this is not enabled yet for agency accounts."

If anything, agencies should have more options than SMBs, not less.

Bing, please implement this for Bing Agency accounts with an unlimited number of listings in it! We need it. Thank you!
