Not sure why, but if I close the site for more than an hour (maybe less?) and come back, I'm logged out, even though I've checked that the option to remember me is ticked. It does this on my phone, ipad and PC. Is this a setting with the site?
Yes, that happens to me too. The site / or my browser? forget the login information anytime the browser is closed.
After closing your browser, when you come back to AG, visit the https and not the http, delete your http favorite link and update it to use https
