I am having the same issue but not on woocommerce products only on the woocommerce category pages… The yoast area box appears on pages but it never finishes loading (readability green circle never stops circling) and when you add title and meta it doesn’t save and keep info added. I have version Version 15.2.1 installed. I tried rolling back to older versions and that didn’t change anything. I did a site health check and nothing pops up but I haven’t started to check plugin by plugin, that will take a lot of time. I don’t see any java script errors popping up. Is this not a known issue on your side yet? I saw multiple people have similar issue..
it worked to rollback to 5.05….I am concerned though with having an outdated plug-in. Is that a bigger vulnerability than getting spam submissions?
