This is my first post.
I get the error message above although I tested my data with Google and the code seems correct. Basically, it is an aggregate review score and individual reviews of a tourist accommodation. Seems that when I save it to the page with the error message, all the reviews are not "seen" by google. The code is long (12 pages) but many repeats of the same review section (about 20 reviews).
Can someone help me?
