Hi @KatC
If 6 weeks has passed the logic conclusion is that your reviews have been checked and found to violate some guidelines.
https://www.localguidesconnect.com/t/common-review-violations/351688
Your efforts as a local guide is limited to only 12 reviews. From experience we know that the spam filter is more critical towards users with very few contributions. This is because spammers often use new accounts to post fake reviews.
You could diversify and expand your contributions and hope the spam filter will understand you are a real person. Adding photos of the places you visit might help.
Or you could share 2-3 of your reviews with Maps links to the places below, and I might be able to spot what you are doing wrong.
Are you managing a business on Google Maps with the same account?
