Is there another website I can use quickly view SMO's WR time? (And no, I'd rather not get email notifications) Because, loading the full leaderboard list takes 18 seconds on my Pixel phone and 43 seconds on my 8yr old Asus laptop.

YouTube i'd imagine...

yea youtube would be the best for you

Youtube or memory for seeing what the wr is, but you can also turn on the notification setting so that when a wr is beaten in a followed game (odyssey), you'll get a speedrun.com notification (little bell next to your username when logged in.) That way you don't have to load the entire leaderboard to see if the wr has beaten, you can just check if you got a notification, which doesn't take a year to load.
