Double login prompt for Apple Communities

For weeks now, whenever I log in here, it asks me twice to either use Touch ID (on my old 2017 MBP) or approve with my Apple Watch. Why? The second prompt does go away after some time on my Watch when using my new MacBook Pro, but on my old one it keeps asking for Touch ID on the Touch Bar even though I've long been logged in. Wouldn't be so annoying if I didn't have to log in ever time I open the website.
