Too buggy Too bad. K-9 used to be great but now it's glitchy  sluggish and looks and feels outdated. My Gmail accounts stop working (login authorization problem) when switching between WiFi and 4G. Yes  K-9 is rich with features but it's still awkward to use. It's just too annoying to deal with. Back too MailDroid  which is much more stable and easier to get around in...
