I was trying to sign up for a paid plan, and the submit button was disabled (not best practice for accessibility, bc guess whaaaaat, a disabled button doesn’t tell you what’s missing to help you move forward) and it took me a WHILE to figure out what was missing - a checkbox that was nearly invisible on my screen.
Of course, while logging into the Figma forum to post this, there was another similarly hard-to-see checkbox to agree to the terms, which even when checked was not as visible as the checked one on the payments page.
Anyway big accessibility fail, probably costing some sales.
