I have a managed WP account with them. They told me it could take a week to a month before they vet the new version. I can wait. 4.5.3 works fine.
Well, I have one website that is on GoDaddy’s cheapest shared hosting and I can see the 4.6 update. So I don’t know what is up with GoDaddy.
I don’t know either but I can wait.
