Always have to log on on Android. I recall a thread a while back where users gave lots of use cases. I think it ended up being 'as designed'.
Here is that thread, with some helpful insight from
Ditte.
I've got an answer to you all regarding "remember me" when logging in through the Single Sign On. We asked internally to understand how the feature is supposed to be working, and got the following answer back:
" "Remember me" is only for remembering the email, and nothing else. It doesn't keep the user logged in or auto log the user in. This is a shared feature of the entire login mechanism."
So, long story short, it's not supposed to auto-login, and InSided can't force that due to data security.
If you do experience a smooth auto login, it's most likely a browser feature or setting.
That said, it should be remembering just your e-mail address. If you would like for your password to be remembered, you may want to take a look at password vaults and other browser tools.
