I too have this issue, I have a client who deleted their review and posted it under a different account, and wants the review to be removed, but it has been over 72 hours, and the old review is still there on the widget, despite it being gone from Google. How do we remove this?
Hi there @p2a 
I am so sorry for all the inconvenience caused by this!
Could you please share a screenshot of the review that should be removed?
