I just downloaded 8.3 ota, and I'm having some email issues. My emails seem to be coming through, but every time I open the app I get "Cannot Get Mail The connection to the server failed" popup. It's not a huge deal since email seems to be working (unless one of the fewer used accounts I have can't access the server). It's just really annoying to have to hit OK every time I open the mail app. Also it pops up periodically if I keep the mail app open longer than 20-30 seconds.
