Hope you are all staying safe and business it doing well. I'm currently having some issues with a mobile version of a theme we bought a few months back. I'm having a lot of customers turn away from our website on a mobile device and I think it's due to the design and functionality. I contacted the developers regarding this and I was told this is a custom request and would have to pay for modifications - Which I'm not really willing to do I'm happy just to educate myself on this.
Where can I locate the files that change the header design in a mobile theme? I have attached an image for the section I'm trying to remove - I don't wish to add code I'm just trying to remove code.
