Edtech A/B tests we've caught

Safari and Firefox (visits 1 and 3) show a different tab order in the 'Get started as a...' role selector: Teacher, Student, District Leader, School Leader, Parent. Chrome and Edge (visits 2, 4, 5) show: Teacher, Parent, Student, School Leader, District Leader. The subheadline copy also differs: Safari/Firefox show 'Free for teachers, forever.' while Chrome/Edge show the same 'Free for teachers, forever.' — actually the hero subhead reads identically. The key difference is the role-tab order and arrangement in the persona selector strip.

The hero headline differs between visits: Safari and Firefox show 'The expert-powered learning platform that drives business growth' while Chrome shows 'Accelerate public sector growth with a learning platform for government'. VWO experiment cookie _vis_opt_exp_39_combi diverges (2 vs 1), confirming an active A/B test on the headline copy.
