Excuse me for the nth ticket about similar issues, but it is hapèpening again (hope you remember the other one. This time is happening on a fresh new website, different host, etc…

The issue:
– With Gutenberg set to “auto” in CPT (so the Classic editor is in use when editing), Taxonomies terms are not updated when changed in backend.
– With Gutenberg set to “enable” in CPT (so Gutenberg is in use when editing), Taxonomies changes are saved but changes made to the content section (standard WP field) are not applied if the text is converted in Gutenberg blocks. You can test by yourself with posts in CPT (Eventi).

TIA
