Was there a change to the content sharing? We had a player that had it enabled, and now the campaign we were in had it disabled.
I have subscribed and enabled, but I'm trying to troubleshoot to know if the aforementioned player actually disabled it.

Thanks!

Unless said player has a Master Tier subscription and therefore the ability to turn content sharing on and off, no, they could not disable it. Are they making the character in the campaign? Is this a new campaign that's been created that is beyond the five active campaign limit for content sharing?

If that player had been the one who had activated content sharing in the first place, then yes they could have disabled it. However their subscription might simply also have expired too.
