Q: my podcast has been approved but I still cannot find it on iTunes; it was approved 4 days ago.

Go to http://podcastsconnect.apple.com and check the third link below the 'Additional Information' header: if it says 'Hidden' click it to unhide your podcast. There have been instances of a bug in the Store causing new podcasts to be hidden from the start.

And please always post your feed and Store page URLs when you have a question: there might be a different cause but one can't tell without looking.
