I have looked for some information on this but can't find any news on it, but it appears that since the banner change on Google+ Profiles and Pages, the Google Map "more info" links are not linked to business pages (specifically, those that have been verified). Anyone else notice this or have information about it?
Upon further review, it appears that it's related to either the issue with the PIN verification screens going to 500 errors or that some listings are marked with quality violations but they don't notify of these violations unless you log into the page and go to edit the listing information (which doesn't make sense because you wouldn't edit information that has been verified!).
without making any changes, I submitted a G+ Local Appeal (even though no violation was present). That was on 3/20, by 3/21 I got notification that everything was fine. Seems a bit of a systemic issue... so everything is not fine but thanks Google. ﻿
Thanks choolateseo, I had not seen reports of that one yet. Will keep my eyes open.
There is another bug reported to Google where URLs to the business site on merged/verified Google+ Local pages are totally missing and at 1st when I read subject of your post I thought that's what you were reporting.
