So have any of you here had clients who've lost all their reviews? We're seeing a lot of that on the Google forum (and for me, privately).

@markbarrus Thank you, and yes, that was spurred by the Mike Blumenthal's tweet. I'm seeing a few like that and am wondering if there are more that haven't come to the forum yet.
@AmyToman haven't seen any yet myself, but I'm starting to keep track of all my CIDs and other information
@markbarrus New path on that. Google now requests the Business Profile ID. Three dots > Business Profile settings > Advanced settings, then it should be at the top. So no more CIDs, just that number. Hope that helps.
@markbarrus @Trankova I am following. Should I do more?
@AmyToman @Trankova Thank you Amy. I just wanted to make sure that Nina had the update, the profile ID vs not the CID
@markbarrus @Trankova Ahh, cool! The ID is much easier to grab. I had a recent business that did not know how to grab the CID and waited almost 3 months to try to figure it out. They sent in a single response with the ID, and the listing came back within a couple of days.
@AmyToman @markbarrus document both actually, older profiles do not have a pid that matches a cid, newer ones do, support also messes up on the pids
