Comcast email not connecting on LG G4

[ellyenne]

I've had comcast POP3 email set up and working on K9 email since the phone came out. It has suddenly stopped working on my LG G4.
My other 6 email accounts are still working perfectly on K9 (yahoo, att, iCloud and mindspring).
I can still download email normally on my Mac using MacMail.
I can still download email on my Droid2 using the default email app (don't ask - I keep it to troubleshoot and play games).
I have installed and tested the default LG mail app, MyMail and they don't work. There have been comments on other email apps that they are not working.
Xfinity Connect works from my LG G4, but functions as a IMAP connection, and deletes email from the server when deleted on the phone, which is obviously NOT what I need.
Does anyone have any suggestions as to what is wrong and how I can fix it?
Is anyone else having this problem?

The settings on the server should be setting whether the account itself is IMAP or POP3. Log into the account on the web and make sure it's set to POP3. If you can't get it to change, or you can't get to the place to change it, call Comcast for assistance in changing it. (The phone app should automatically pick up which account it is when it tries to connect to the account - evidently it's getting the wrong information.)

After a couple of rounds with Comcast technical "support", that did not fix the problem, I found that I could always connect immediately after booting the phone. BUT, it would stop working after that. Obviously there was some sort of problem with the server not "clearing" some setting. Luckily, the problem self corrected - Comcast must have fixed it.
