It finally got so bad I had to go to Blue Mail. It works great. K9 stopped pushing  no notification sound or led. This was on both the LG G5  and Galaxy S8. K9 just does not work any more. I used it for years then it just crapped out. What happened? I would love to know how this went from one of the best email apps to one of the worst. Just look at the ratings. I remember when it had like a 4.8. Now it's junk. Use blue mail. Much better.
