Thx, I was just looking at https://groups.google.com/d/topic/k-9-mail/F8V0kmcWJ-w/discussion (should have searched a bit harder before posting) which suggests the power setting change and I'll save that in case some other things don't do it.
When I tried: Global Settings > Network > Background sync: changed it > from "Always" to "When 'Auto-sync' is checked, K-9 immediately did a sync, plus it auto-synced another message a few seconds ago. But since my problem is intermittent I can't be sure there is a causal relationship. I also see where in Settings->Folder Settings->Folder Poll class, my Inbox was set to "None", and I've set that to "1st Class"--I was just ASSUMEng my Inbox would be First Class but I guess that's just my vanity talking. This may take a while, thx for the suggestion, I'll let you know. --gvc On Thursday, June 27, 2019 at 5:57:32 PM UTC-4, Mathguy wrote: > Have you changed the Android system settings so K9 is NOT battery > optimized? > -- > Sent from my mobile device.
