First visit to icloud.com lands on a spinning wheel. Allowing all cookies for the site will fix this and land on a login page.
However, I discovered that if I later flip the cookies setting under shields back to 3rd-party cookies blocked that it breaks the site and I’m stuck with the following cookies need to be enabled no matter if I reenable them or turn shields off (a little fuzzy on the steps, but I may have also turned shields off and on after that):
I have tried Site settings > Clear data doesn’t help and no matter what I try, I seem to be stuck on the iCloud requires cookies page, even if I bring the shields down. I also tried clearing all browser data, but no go.
I have had to uninstall and reinstall Brave to get around this, but I fear that this symptom will reoccur on other sites as well.
It would be great is this didn’t happen, but in the event it does, is there a way that I can truly reset the site to get back in? The workaround is to use a Guest Window. Even a Private Window is hosed when trying to reach icloud.com after the above happens.
