I have installed k9 mail from fdroid v.5.600 on a little x3 pro. The problem is that the app does not sync in the background, I have checked the app settings and is sync enabled in the network options. I previously used the app on a xiaomi MI A1 with android 9 and it synced correctly but on the Poco x3 pro with android 11 it does not.
Is it a problem with the app or some incompatibility with MIUI or android 11?
