I'm having an issue where none of my campaigns made after March 1st, 2025 no longer allow me to share content with my players. I've tried to edit them, delete and recreate them or create new from scratch. Did I miss an update that allows sharing across all campaigns regardless? Is there something else I'm missing? I have players who are missing options I know I have purchased/unlocked. 

There is a limit to how many campaigns you can share content in at one time.  I think it is five.  Have you exceeded that limit?
