2 products per row on Mobile view - CSS randomly stopped working

Hi all, is anyone having issues with their products no longer showing as 2 in the one row on mobile view now? 

I used CSS months ago to set up the product view like that when using your phone, and all was fine it worked and showed 2 products per row and has been fine for months. Suddenly over night it seems something has happened and the code no longer works? Products are just stacked on top of each other even with the custom code being pasted in the CSS part still. It's worked fine for months and randomly isn't working now - any advice as I checked a few other websites out that I know use squarespace and it has happened to them now aswell! 

OMG IT WORKS! Thank you so much for your help!! You are a LIFESAVER 🙂
