GitHub Pages not updating!

I deleted and reuploaded a HTML file to my page… it’s been so long, and it hasn’t changed. Still 404. Yes, I have pages on. Yes, other pages exist. No, it’s not big! 2.4MB is not big in ANY WAY! My page is a passion project I add and edit for fun, and as a stress reliever, not to stress me more! It’s super annoying, all of my pages take so long to update or even show up, and I have good Wi-Fi. Always happens. Never found a way to fix it. I’ve provided screenshots too. Please help me out!

It shows  up now, but still took over 20 minutes to update for 2 megabytes. Still need help with the timing!
