Campaign Content Sharing Error

Just wondering if anyone has had an issue with campaign content sharing?

I have the master tier subscription and have a handful of campaigns active for people to test builds in. However, I recently have been unable to share content on my most recent campaigns (i.e. one made today at 05/11/2025). I checked the campaign, reloaded the page, signed out and back in, and also checked the option on a different campaign.
 
Any ideas what this issue is and/or how to fix it?

Thank you for explaining that. I figured there was some sort of cap to it to prevent infinite content sharing.
