Why is the Impact theme not working properly on mobile?

[index555]

Hello all,

since a few days the theme Impact works only conditionally on mobile. ( In the preview it is flawless, the desktop variant is also perfectly ok) If I open the store, I can no longer scroll and images are displayed much too large and are cut off at the sides.
So far everything was ok. Until a few days ago. What could it be?
