Jetpack error when user with Author role submits post for review

I’ve spent all day looking for a fix and decided it’s time to finally ask here. I have a website that allows users with Author role to submit post for review, however, they’ve been seeing an error saying “Updating failed. Sorry, you are not allowed to edit the jetpack_post_was_ever_published custom field.” whenever they do so. I notice too that there’s this notification saying “Sorry, you are not allowed to do that” whenever the Newsletter component is clicked.

While the post is successfully submitted and appears in the Pending tab, it fails to register certain associated information such as Notes and an ACF custom field for an alternative headline. These remain blank while the taxonomies get saved just fine.

I temporarily implemented a workaround by adding a code snippet that deactivates Jetpack when the current user is an Author, Contributor, etc., which works, but it somehow causes the front-end to break when the same users view the site, so I’m thinking there must be a better fix for this issue. I have contacted my host to no avail.

Any input is appreciated.
