Used K-9 successfully for quite some time, then it stopped working after the update. Tried reinstalling and now when I go into the settings and change the folder poll check frequency to 15 minutes it changes back to "never" every time! I use K-9 to push my MSN email and the stock email tells me repeatedly during the day about the same emails over and over, even once I've read them, so using it is not very appealing either at this point. Thanks in advance for any advice/suggestions.
