Hopefully this will fix the missing badges on iMessage on my iPad.
I hope so too. My mom has been dealing with this with her brand new iPad 6th gen. We’ve been round and round with Apple. Its ridiculous...
I had the missing iMessage badges problem on my iPad Pro, as well. Since 11.3, I think.
Simply updating to 11.4.1 did not fix it.
So I erased all content and settings then restored to an iTunes backup.
Now I have the badges functioning again.
