Hey there nguyenthixuan151,
Sorry for the delay on this one ??
I added more tag to a post, and set protection rule for More Tag that everyone can see
I’m assuming you’ve set protection rules in Membership 2 -> Protection Rules -> Comments & More Tag -> “Hide read more content”?
I’ve tested this using the same exact rules, single post in admin https://screencast.com/t/d0TII3o0nvC, protection rules https://screencast.com/t/Cvv70SLjDCr and this is how it looks on the front end https://screencast.com/t/u25ISYFu (both blog page and single post pages).
I’m assuming the reason for that is because you’ve also used Individual Posts protection which by design hide the posts on blog/archive pages if a user doesn’t have level with access to those posts so please try deactivating that and use the above.
Hope this helps ??
Best regards,
Bojan
