Some weeks ago, my auto-sync stopped working after working properly for a long time. Manual sync works just fine. It happened when I temporarily changed my Defaullt Account and message display count, but there might have been an update around then too. I don’t’ recall changing any other settings at that time.
I have 3 email accounts in K-9, but only want to auto-sync one of them. I can include my exported settings for that account if it might be helpful. If it matters, I also POP emails to my laptop daily, and delete those from the server.
I hope someone can help me troubleshoot this, there are emails in one of my accounts that I need to receive very quickly, and I can’t constantly be manually checking email. I’ve searched forum posts here and elsewhere, and have not found anything to correct the problem.
