I’m having the same issue.. Its starts working but after a while it stops. Tried several installations, different hosts and everything. One of my themes seems to work better with it (arras) the others jam within a time frame.
Good to know you are working on it, this is by far the best instagram plugin and I use it a lot! If its possible I would like to make a donation to help its development. (I can’t afford much, but at least might buy you a lunch or something =))
