Hi there!

I found the other thread (71979-Channel-admin-cannot-set-subscribe-power-insufficient-permission-modify-power) with the exact same title (copied it from there). Was closed years ago. Would have re-used it otherwise, as my problem is exactly the same except that I have set (in my opinion) proper grant values.

I also have read the 70147-Permissions-system-quot-First-aid-quot-kit thread. The solution there did not help me, as the grant values should be just fine. So I'd really appreciate being enlightened by someone who understands the permission system better than me.

TLDR: Why can't a channel admin set needed subscribe power?
