The website runs perfectly fine for me (I have a Lenovo laptop from maybe 2017-2018), but on my Surface Go 2 (which I got in the start of 2022), it does lag. I use Chrome on my laptop and Internet Explorer on my tablet. Maybe it's the fact my Go 2's on-screen keyboard makes the page jump to the top and back down every time I press backspace. Factors!
