I recently switched to K9 mail in order to be able ot use the email popup notification. However, I'm not happy with it at all right now. It seems that the program is not pushing my emails upon arrival. I have to manually go into the program and say "refresh". Obviously, this defeats the whole purpose of having the email pop up. Just a side note, I receive my emails instantly with the stock email app, so as of now, I'm going to stick with that. Does anyone have any suggestions or ideas about this?
