Problem with unified folder

I have enabled Unified view for folders to display emails from all my accounts. Yesterday I added one more account. But emails from that account don’t deliver into Inbox folder and displayed separately only. How to fix it?

Are you getting any relevant error console messages? Does switching away from the unified view and back to it help at all?

Not sure where to look at console errors, but I hadn’t seen any warning messages. Changing view back and forth don’t change anything.
