Ratings and reviews

New user. So far good experience. Everything looks and functions well. Look forward to utilizing the email. Do not see a way to log out of the app. When composing an email the recipient's address was hidden now it shows up. Do not know how to change. It is synced to use with another email provider only shows their information.

It crashed many times during setup. Can't get passed setup. Edited: After numerous attempts I identified the step at which the setup was crashing. After typing the password to log into my email account, making the PW visible would crash the app. Finally, I set it up. Nice app, simple, not many bells and whistles, works well with Google, Microsoft.

I loved K-9 before this update. But now it's so hard to distinguish between my accounts in the menu. Before, I'd given each one a different profile pic and color, so I always knew which account I was looking at. They also appeared in a set order, so I could navigate easily. Now 4 of my 5 accounts are labeled "GM," and the highlight color is the same for all 5. What?! AND each time I open an account, the list order shifts, so they're never in a predictable order! Wish there were a way to revert.
