    Curious if anybody else has had the same problem as me with this app. I have several emails and every few days I have to re-login because for some reason my passwords are not staying authenticated for this app. This happens with all of my email accounts and it only happens in this app for Android. ANybody else notice that they have to login again very often, it is annoying since my passwords are super long and complex Lastpass generated that I do not memorize and I always have to go on my computer and go into lastpass to find out what each password is,
