Notifications Don’t Update
App worked great for a while, but then it stopped syncing with my computer. My emails would be constantly marked as unread, even if I read them. Even after I deleted emails, they would show up in the app as new and unread emails. My inbox became flooded with things that I had already taken care of.
I ended up deleting it and now use Apple Mail.
