Tabs not changing :(

Hey everyone, hope you are all well. I am having trouble whereby on my mobile phone, i am able to switch between the tabs on the “What We Do” page (the arrows as shown below in the screenshots) - but i am unable to do this on my laptop / computer.

Even the buttons like “built with passion” and the button below it “what we do”, i can click and it takes me to the linked pages on my phone but just unresponsive on computer/laptop.

thank you for taking the time to read this and help me, i really appreciate it thank you! <3 <3
