@Seba, two small things for your euc.world website bug list:
a) in Chrome (currently on v83), while viewing a tour, the vertical scrollbar does not work properly. While using the mouse wheel is ok, most of the times you try to use the scrollbar, it just moves a few pixels then gets stuck (works fine in Edge): to reproduce, scroll to the top with the mous wheel, grab the scrollbar and try to go down. In my case it fails at least 50% of the times.
b) IE11 stays "Loading" forever when trying to open a tour (in this case, your https://euc.world/latest/Seba )
I tried in two different PCs.
