I think there’s a way to just clear data associated with *.scouting.org sites. There was a post that mentioned it a while ago…
ETA:
Chrome → Settings (under ellipsis at right) → Privacy and Security (under left side hamburger menu) → Third-party Cookies → See all site data and permissions
Then select the scouting.org sites and clear the data.
ETA2:
Similarly, for Firefox, you can selectively clear data this way:
Firefox → Settings (under right side hamburger menu) → Settings → Privacy & security → Manage data (under Cookies & Site Data)
Then select the scouting.org sites and clear the data.
