Manual Fetch Only - Sync Disabled - Known K-9 Problem

[right...@gmail.com]

As usual, it appears that no sync on Android S7 is a known bug and has appeared in the bug tracker for a long time.  It has NOT been resolved.  Unfortunately, the K-9 people have not included this information in their FAQ.  Thanks K-9.

Please refer to https://github.com/k9mail/k-9/issues   ...this link is the bug list for K-9.  Please refer to bug 2618, which is a continuation of bug 2357, which is a continuation of another earlier bug.  Same description, no sync with Android S7 with the latest K-9 version.

One or two people have checked into battery saving as the reason for no-sync. At best, it is a workaround for only a few people.  That means that K-9 is not able to wake up the phone to fetch mail, and that is a bug.  For most, disabling battery saving for K-9 does not work. 

I did find a screen of permissions in the K-9 program under Settings/Apps/K-9/Permissions.  Under "Additional Permissions" there are 4 choices which are all truncated so you can't read what they are or what they do.  Personally I do NOT want K-9 to read and update my Contacts list or interact with the Play Store or my Calendar.  I can't even.  Sometimes, I can press one of these truncated permissions and a message comes up telling me that these permissions are for a previous version of K-9, or that K-9 needs to be updated.  Not too helpful.

So, summary is that the problem is known and has not been noted on the K-9 FAQ.  Presently there does not seem to be a fix, or even a message saying that they are working on a fix.

Time to look for another email app, I guess.

I'll repost my earlier message explaining exactly what settings made
things work for me on a Galaxy S7. I haven't seen anyone say that
they tried these exact settings and still had a problem. I've been
using these settings for months now and they continue to work for me.

I'd prefer to have Sync ON all the time. How can I make that happen?

Same here.  I'd be happy if manual sync worked to get around this issue but most of the time it says Sync Disabled No Network.  And no amount of manually refreshing or hitting the sync button will sync new emails.  I've gone all day trying this work around with no new mail able to come in even though I can see it out on the ISP's website.

Wonder what is another email program that would be good to switch to for replacing K9 since they don't care to fix it?

Thanks,

Cindy
