We just released an update which changes how we handle SSO, a full description of the changes will be posted in c/changelogs once the update is stable.
Please use this thread to notify of any issues with things like being logged out, being redirected to the old domain, etc. If you have a bug report, please also include what browser (ex. "Chrome") and version (ex. "89.0.4389.90") you're using, and whether you're using any privacy blocking extensions.
If you do get "logged out", it may not be as it appears. There's two options: for some browsers, you can wait a few seconds and you'll be automatically logged back in. If you aren't, then you can click the sign in button, and you may be immediately logged back in without having to re-enter any details. This would be the intended behavior for some privacy focused browsers and extensions, as well as some old browsers.
A couple of months ago I received an update on my phone. I don't even remember if it was Samsung, Verizon or Chrome. Ever since, I have no icons on the bottom of my phone (Back, Close, etc.) Makes it hard to us. If I want to close it I have to start the phone turn off process and then I close all.
