Random products are giving me the same problem. The "@id" /#Product string has worked perfectly for me up to now; nothing on my end has changed either.
A "Missing field'review' (optional)" error appears in GSC and Rich Results Test, yet the previous Structured Data Tool and GSC test the live URL with no problems.
To no avail, I've tried everything else: reindexing, clearing caches, re-creating structured data, etc. I can see that "page actions are temporarily disabled," but might this be a problem while Google is changing their services??
