Joy Website

Joy Design Studio is a furniture store that operates both on e-commerce and physical store. We have previously re-did our website and still need a few tweaking here and there. We can say the website is now working as we want to, but the mobile version is not working as smoothly. These are the issues at hand (mobile version): 1. Under the hamburger menu, the sub-categories are not displayed under the main categories. Visitor will have to click on the drop-down in order for the categories to show which we think is not very user-friendly. (Screenshot attached) 2. The product image on all categories is too small on the mobile interface. Are there any ways to make the product viewing bigger? (Screenshot attached) 3. At the moment there is no analytics linking our website to our Facebook page and Instagram accounts. Something like Pixel to link our accounts. The issue here is that we don't have the access to the backend to install the extension.
