reviews not showing up

Reviews exist but don’t appear in Search or Maps. Start with the page that matches what you are seeing.

Pages

Which one is yours?

Google rating or review count not updatingNew reviews are on the profile but the star rating or the number beside it has not moved. Google's own answer is that the score lags.
Reviews not showing on Google MapsNo reviews on Maps at all usually means the profile is not showing, not that the reviews went missing. Verification, suspension and timing explain most of it.

Platforms

Which platform?

Google first. The others are being written, and are not linked until they exist.
