K-9 mail background sync not working, I tried network>background sync>always
- What K-9 Mail version are you using?
- What Android version and device are you using?
- What exactly do you mean by “not working”? Does the message list contain new messages when you open the app, but you weren’t notified about them? Or do you only see new messages after manually refreshing a folder?
- Did you set up automatic polling?
Account settings > Fetching mail > Folder poll frequency
- Are the folders you want to poll automatically configured correctly? Check out the folder classes documentation.
