Hi everyone
I'm sorry you have been having problems. Nothing has changed about the way we log you in or anything to do with the remember me function since we started using this platform about six years ago. It may be that when your browser software is updated, cookies are lost and/or cookie permissions change. However, there are so many browser/OS combinations now, and so many updates to both, it would be impossible to keep changing the login functionality to keep up. Having said that, I mostly use Chrome or Firefox on Windows 7, and never experience any problems with this, and am logged in all day and every day.
I think this is generally a problem to do with individual browsers not keeping hold of your cookies. When I used a Mac years ago, I had problems with timeouts logging me out periodically, but I have never had this with any other Windows/browser combination. I spent quite some time trying to find out why this happened, but never found a fix for it.
I suspect Ipads/Iphones may suffer from the same problem as my old Mac did. I don't have access to any Apple devices other than an ipod, so I am not able to reproduce this though.
Whatever OS/Browser you use, you can only stay logged in on one device at a time, if you log in on one device, you will be logged out on another.
All I can say really is that nothing has changed here, I think 'remember me' has never really worked well on IOS, so if you have recently started using an IOS device, that may be the problem. On other configurations, it may be that subtle changes have been made to individual users browsers/devices at particular times which affect 'remember me' temporarily.
