my nexus 4 cell phone upgraded to android 5.0 lollipop, and now it doesn't want to download my POP3 or IMAP emails (used to work fine in Android 4.4) It just gets stuck in "getting your messages" - even for 2 hours.
It does download my GMAIL accounts and Hotmail account properly.
I setup the accounts manually (as I always did in previous upgrades..it worked fine).
