Been using K9 for nearly 4 years now very user friendly and has performed all what such App should have. However, right now it allow mail movement to another folders within the same email ID but it would be better if it allow mails to be able to move from different email ID. K9 team please consider as many folks out there believe is using more then I email ID

Have used, loved and recommended K-9 for ages, but it has stopped notifying me of emails. Sometimes it does, sometimes it doesn't and I have to refresh manually. I gave no idea why. This random intermittent bug makes it no good for me any more. I've missed too many important emails...

Used K9 for many years but now notifications totally not working on Android 6.0.1 Galaxy A5. In spite of settings configured to notify of incoming emails. Have to dump this and use Gmail app, which notifications work ok. Latest v5.208 still not working properly. There's still no email notifications when any email comes in. The only way to know if there's any new emails is to manually open the app.

K9 Ver 5.208 Samsung S7. Been using K9 for several years on older S4 device, loved it. With newer android K9 will not reliably get email. Mostly I have to manually request it. I have tried several of the claimed tips to fix it. I had hoped the claim of the problem being fixed for this version was true. Nope, after a couple of days use, not fixed. I'm tired of fighting it. I really wish it was fixed but I'm wasting my time with it.

I like this program, it has been very stable for years, however after upgrade to Android 7 the ringtone has broken and now it nolonger auto downloads mail, this is a key feature so am disappointed . I can manually download but this is not so good I expect to be told when I got mail..
