If your shop looks a bit like this:
Then it usually means you've got most of the items already - awesome!
We get that it looks a bit weird, but your shop should update when it next refreshes or when new items or added. Check back in a few days to see what's new! Feature items usually rotate every 3-4 days or until we add new items.
We're aware that some items are currently missing from the shop rotation and we're working on adding them in. We're hoping to have this completed by Season 6. In the meantime, don't worry if you see a few boxes saying "coming soon" - it just means you already own the items currently in the store!
If your shop still looks completely bare after 4 days, then contact Support including a screenshot or picture of your Shop, your Support ID, and the last time you saw items in it or you were able to make a purchase.
