I used to love Wolfram Alpha but it hasn't worked for me for several years and I've been unable to find out why. Just tested now and it does work on Android FF - yay! But not on my desktop (neither Chrome nor Edge). Doesn't work for me on Firefox nor Brave either (neither Win10 nor Kubuntu). I have randomly assigned IP from major UK provider (which provider has also changed). Doesn't work through my work VPN either. I've taken to using Geogebra (online) when I quickly need a function plotting.
