[Evolution] Evolution keeps asking for my passwords

[Steven Taylor <steven taylor56 sbcglobal net>]

Hi, I have had evolution 3.36.4-0ubuntu1 running for about a week now
on my Kubuntu 20.04 system and it has been fine. Today, when I booted
the system, it said an application wanted access to my keyring so I
entered my password for that and started Evolution. Now every time
Evolution checks my mail, it asks for my email passwords, I put them
in, sometimes leaveing the "Store password in the keyring" box checked,
sometimes with the box cleared. Everytime, it goes ahead and retrieves
my mail okay, but the next time, it asks for the password again. It has
never done this before now and I haven't made any changes. I am about
ready to go back to Opera as my mail client.
