Make the individual category permission of community site work
As we know, we can create more categories in the community site. For certain categories, I only want most people to read instead of posting things. So I set the specific permission for those categories by editing page permission. However, the permission setting is totally useless. No matter how I set it, it won't affect the permission on that individual category at all. If it is not working, why do you still show it to me and let me modify it.
My suggestion is you either make it work or disable it.
