Went to see if I could cancel my Claude pro plan just now. On billing I see adjust plan button. On that page I can upgrade but no where can I find downgrade/cancel. I checked the account page. I see delete account but "To delete your account, please cancel your Claude Pro subscription first."

Update: below the fold at the bottom of the Billing page is the cancel section and cancel button.

Update 2: just clicked cancel and was offered a promo of 20% off for three months...

Update 3: FYI, I logged in to my Claude account via computer (not iOS or Android).
