Quizz Display trouble

Hello everyone,

Yesterday, several users (in different centers) had Quizz display troubles. Here are some examples: 

They were on Google Chrome or Edge, but I have no more details since I wasn't there.

Do you know if the problem was caused because of a Chrome or Edge version?

It really is an issue since the quizzes are final exam to validate professional trainings.

Thank you in advance for your help.

Regards,

Veronique.
