Mobile View not updating

Hey guys,

my homepage is working just fine on the desktop view, and also if i use chrome to show me the mobile views its showing me a nice view. However, when I’m opening my homepage on my phone its not updating anything. So theres an wrong menu, wrong pictures, the slider didnt update and stuff like that. Do you have any idea what could be the problem? Thank you so much for the help!
