I can confirm from your public profile that you have added 1784 reviews and only 1239 of them are public.
Google has automatic filters that hide your reviews so only you can see them. This can happen when some of your reviews violate the review guidelines.
Read about typical review guideline violations here. And please see my latest post called 4 Tips on writing better reviews. Judging from your public reviews you often share very short reviews without explaining any details from your visit. Generally remarkes are not very helpful. “Another private beach. :(” is one example.
If you want to identify which of your reviews are hidden check this post.
After making your reviews confirm better with the guidelines, please use the form called Account investigation for contributions not visible on Google Maps if you believe that some of your contributions have been wrongfully unpublished. Keep in mind, it takes several weeks for the check to be done, and you will not be notified about the result, so I suggest you check the status of your reviews once a week or so.
