Unable to access or use Github in Safari after iOS 15 update

The topic title pretty much states it all …

I updated my phone to iOS 15 a week or so after it launched, and have since been unable to update, edit, download, merge, push issues or commits, or simply put … use any function on the website, not the app, since.

I’ve cleared safari, all website data
I’ve reset all network settings
Ive followed every guide or tip I’ve come across, but have come up empty handed.

I suspect the issue(s) lie within the experimental WebKit features, but havent the slightest idea of what it’d be. Any information or ideally, a resolve would be most welcome. Thanks in advance!

Not seeing that on my 10.5" iPad Pro, but I’m a mostly passive user of GitHub.
