A couple of months ago I joined a campaign and had access to all of the source books to release. As of yesterday, I do not. I do not know why, but I have reached out to someone else in the campaign and the DM of it, to see if they have access to it and if he turned it off. Is it possible that the content sharing could be bugged?

One person in the campaign must have a master tier sub and have enabled content sharing. Sometimes content sharing breaks and it needs to be turned off and on again.

So in order, I would check:

• Does someone in the campaign still have a master tier sub
• Do they have it enabled
• If yes to both of the above, turn it on and then off again

Am I able to check these things? If so, How?

Yes, in the campaign page right under the name, you should see a box that says "Content sharing has been enabled by XYZ" like below:

It doesn't say that, it just says "Random Characters" nothing else. So no more content library I guess, but thank you for the help
