Railway: “We identified the source of the issue is [the] ban of Flash content” (twitter.com)

A very large financial institution of which I'm a customer was apparently using Flash right up until the cutoff, and also specifically required it for virtual credit card numbers (which I never used for that reason).

I wonder what the status of the site is now...

Yup, I still get the warning Flash is blocked when I log in...

The virtual account numbers appear to work...? In spite of the puzzle piece indicating Flash is being blocked. How odd.
