Identify the actual symptom#
Check whether the author still sees the review, whether it is absent in both Search and Maps, and whether one or many reviews are affected. Do not ask the author to repost the same text repeatedly.
Google says reviews may take several days to appear while they are checked. Reviews removed for spam or policy violations are not restored. Merged profiles may also need time before reviews display together, and reinstated profiles can present special cases.
Wait a few days for a new review, confirm the correct location and check for duplicate or recently changed profiles. Review the official missing reviews guidance and contact Business Profile Support when the documented situation applies.
Never compensate with fake reviews, bulk posting or incentives. Continue asking all genuine customers neutrally.
