Hey calpollion   Thank you for submitting this issue - we will be investigating this ASAP.   TO get some potentials out of the way:

Does the world you are trying to edit content trees (or any other advanced features) belong to you? (as in you are not a co-author you are the owner)

Just in case, have you tried logging out and in again?

Hi Dimitris!   Thanks for getting back to me so quickly. I've actually managed to determine the cause of the issue. I was attempting to use these features on a world co-owned with a non-grandmaster user. I've since started a new world in which I'm the sole owner, and this seems to have fixed the issue. Thank you very much for looking into this, but I think this is sorted now!

Hey calpollion - no worries at all! I am glad it is resolved!
