I see an ad when I am taking a course

It’s harder to concentrate when there is an unclosable ad that is covered up by the questions. I assume this is intentional (because all commercial companies are just bottomless bits with endless desire for money), but if not can you please fix this? Thanks.

Hi @anordiaryuser we have tried to reproduce this and haven’t been able to. This is certainly not intentional. Is this something that happens repeatedly or was it just one instance?
