I did a pretty thorough functionality test on 3 locations (did not try the adding over 5 images). But I did notice what I was not sure if was glitch or not, one of my sites loaded with 3 pictures that I can only speculate the exact status on them but looked like a placeholder for an old pic that was no longer there. Other than that my picutures loaded np. But I noticed an issue on when switching straight to google search from wix gmb widget it did not recognise you as owner of the gmb.
Even so, love the app
