Hello @SinaFX,
all our reviews are checked by an AI filter for obeying the rules, SPAM or false information. If there is only a little doubt, they will not be published, but Google never tells us why this happened.
Not only the text of the reviews, but also the content of attached photos and videos are checked. If only one photo is rejected, the entire review including all other attached media are hidden. Therefore, as a first step, I suggest to remove any attached photos and watch, whether text-only is accepted.
From your profile I can tell, 10 of our reviews, 4 ratings and 7 photos are currently hidden.
