I think I found a work around.
I have comcast emails going to my outlook on my computer, xfinity website and on my Verizon Samsung Galaxy note 9.
If I marked emails as not spam on my computer or xfiniyt website , it wouldn't save the changes.
When I marked it as not junk on by Galaxy, it saved the changes and now I get all the not spam emails on all three devices.
Now at least I can respond to all the emails.
I hope this helps.
