Question: I created a public link for a group of testers but the link shows: "***This beta isn't accepting any new testers right now.***"

The build has been approved and I set the limit to 10 testers.

Why is the public link not accepting new beta testers?

Answer: 
If, like I found, you're finding clicking "Notify Testers" still doesn't work as outlined in Ricardo's post, give it 10 minutes to propagate across Apple's networks.
If it says that, it may mean that the app you are trying to install dont want anymore poeple 'testing' their app. or it could mean the link has expired
