Background image blurry on mobile

Site URL: https://rotor-film.squarespace.com

Dear All,

All of a sudden (must have been some change at squarespace) I have an issue with my website:

The first hero background image on the home / landing page is blurry / low resolution on mobile (iOS 14 / iPhone7).  If you look at the "Where Stories Unfold" slogan in the middle of the image, you notice it looks like heavy jpeg compression, on desktop everything looks flawless.

Again, I didnt change anything on my website, it just appeared one day.

Can anyone help?

Best, Gregor

Looks like a Squarespace bug to me, so I would contact Squarespace support if I were you😊
