Here you go:
Use your mouse to:
Click 3 Dots Upper Right>Settings>(scroll down) Click Advanced. Clicking Advanced will expand the current window, set the first option to OFF, default is ON. Close your browser to set the new setting in place.
Likely what happened is your version of ASB automatically updated to the latest version 71.0.1037.99. When that happened some settings were set back to default.
[EDIT:] Sorry to say, but I do not auto-sign in so you may see the setting set to OFF instead....Turn ON...
