Google has been automatically upgrading Google Place listings from the old system to the new Google Places dashboard. With this upgrade, there may be conflicts that prevents the upgrade from completing. The latest conflict is that there are duplicate listing issues and Google needs you to step in, fix the issue and then complete the upgrade process.
Google has recently began sending out notices of the duplicate place listings conflict via email to those impacted by this issue. The email reads:
Jade Wang from Google posted a detailed how to fix this issue in the Google Business Help forums where she summed up the issues two-fold:
(1) Your account and another account that you don’t control became verified for the same business using the old Places dashboard.
(2) You may have verified the page multiple times using accounts you control.
Each has their own method of resolving, which Google has either emailed the business owner or you can read them below in more detail.
