We're so sorry for the delay in response. Could you please test the prototype on a different browser and check if renders correctly or not? If it still doesn't work, will it be possible for you to share the file with us so that we can test this on our end? If yes, please add the file to the shared location and share the link through DM by clicking on my name.
Notes: While sending DM, please add this discussion link in the subject.
The scaling problem has been solved, but I'm still not sure if it was a bug or not. I don't know why, but the scrolling property of my artboard was set to none, but I don't remember changing this option ... Anyway.
The second problem has not been solved. It happens in the footer that is in the file that I'm going to send you. This problem happens in the new Edge, Chrome and Firefox, but it does not happen in Brave.
