Sharing Compendium not working?

Picked up PHB to add to my list of purchased books (Bundle with Xanathar's). The "Share Compendium with Players" option is defaulting to "No" each time I load the page, even if I click YES and Click to save at the bottom. And no matter what I do, I get the denied symbol when the mouse is hovered over the "Compendium Sharing Slot Available". Current players says 6 out of 10. Log off and log in makes no difference. Waited a couple hours and came back to check it and no difference. Am I missing something?

I just tried to duplicate this, and I had the same issue!  If you're doing something wrong, then it's something I'm doing as well.

Ok, after some collaboration with the dev (Drespar pointing out a button), The issue is probably that you are clicking "Save Changes" at the bottom of the page, not "Save Compendium Changes" below the compendium section (right above the Character Sheet Section).  Selecting "Yes" and then clicking that "Save Compendium Changes" button worked for me.

Tested and confirmed - that was precisely it! Issue resolved, thanks for your timely response. I had completely overlooked the "Save Compendium Settings" option.

Great!
