Hi. I've already asked this in the "DM Only" section, but just in case, I'll ask it here too. 

I've been using this platform to manage my players characters during campaigns and to build encounters (good tool but needs a few tweaks in my opinion), and more recently the maps tool, which has saved me quite a buck from printing and laminating the maps since wee just put an old TV flat on the table and put the map there. But I'm preparing for a new campaign and I've found myself unable to activate the "Content Sharing" option, which is frustrating me a bit since not all my players are veterans and don't know if they'll buy the new books yet. One of the players, a kid, have heard about teleporting elfs (Mordenkainen's Shadar´Kai) from one of the more veteran players, and can't make his parent buy that one specific book for a campaign, so sharing it with my players, since I already have it, would be great. Anyone knows how to get that option again?

Thankful anyways, an ever-learning DM

A Master Tier subscriber can enable Content Sharing in up to five campaigns. If you’ve already reached that limit, you’ll need to remove it from an existing campaign first (or have another Master Tier subscriber in the campaign activate it instead).

I think it kind of should be specified somewhere? I checked my subscription and I didn't find anything about a campaign limit 🤔

I can delete a couple old ones I kept on the ready for ocassions 

Thanks a lot, I'll take a look at it soon :)

From the subscriptions page:

How does content sharing work?

Master Tier subscribers are able to share their content with up to 12 people across 5 campaigns. Once you’ve created a campaign on the Campaigns page, open it and select Enable Content Sharing. Any Master Tier subscriber within the campaign can choose to share content.

This page goes more in depth as well:

 Thanks a lot. May I advise to put the limit of sharing in campaigns somehwere on the page when deciding for a subscription? Didn't even manage to get to the page you linked when checking the support page

You don't have to delete any of your campaigns. You can either turn off content sharing for them or deactivate them. Both will free up a slot to enable content sharing in the new campaign.
