Is it a common problem, or I have an issue with my install ?
Thank you for info
About a week ago, my Marketplace was constantly grayed out. I kept coming here to see if there were server issues, but I saw none reported.
I started stepping through my sim settings, and completely unbeknownst to me, all of my various online connectivity options were off! No idea how it happened, but that was my issue.
Make sure your Data Options are all ON.
Go to options → general → data → online functionality and switch from off to on.
Thank you all!
That was the issue.
