Website works fine on Beta build.

Hi @causefx 

I just tried logging in, Version 80.0.355.0 (Official build) canary (64-bit) no problem

try clearing browser data

edge://settings/clearBrowserData

or are you trying to do any special task in there that causes the error?

[#3]

You are correct, Trying incog worked. Not sure why I didnt try that first. Thanks!

@HotCakeX 

Nailed down the issue.  It was my PIA browser extension.  I had Disable Website Referrer on which cause the site to break... Sorry

[#5]

Oh hah, thanks for sharing it, could be useful to know that these things can break some websites! good job

@causefx Thanks for posting this. I didn't think this extension would be the culprit as I wasn't logged into a PIA server. The extension is breaking iCloud even if you're logged out of the PIA servers... Looks like they made a change to the extension where certain features are enabled all the time, regardless if you're logged into a PIA server or not:

"Enabled settings are now always active whether you are connected to a region or not, with the exception of PIA MACE™ which is only active when you are connected to a region."

@causefx Thank you. My PIA settings were blocking iCLOUD for me too and your solution worked.
