Do you mind trying this with the shields down? Being it doesn’t redirect, it sounds like something might be accidentally blocked. (I don’t have an account there nor such a key to test this personally).
I tried it with shields down and I didn’t work. But I also tried it in an private browser tab and here it works with no problems then I tried it again in normal browsing and it works. Seems it fixed itself thanks for your help
On one hand, I’m super glad it fixed itself for you. (Maybe the shields being down temporarily allowed “some” cookie on, but didn’t happen right away?) On the other, issues that fix themselves happen to be the ones that tend to return.
