So far so good. I installed this on my Lenovo tablet to replace an email app that wouldn't push mail anymore since upgrading to Android 6. With this app emails are received instantly, quicker than other devices I have that do support IMAP idle (push). Nice!
It works but doesn't let you cut and paste across apps which is very frustrating
I love it
