This was brought up by someone else and I was able to verify it alongside one other person. Attempting to go to the page to enter your payment info results in a completely blank page. This was tested on Chrome Version 86.0.4240.75. Additionally, this was only tested with Premium, and is untested for standard users (but I assume it goes to the same page).
To reproduce:
- Navigate to the “Buy Robux” page https://www.roblox.com/upgrades/robux
- Select any option. The next page should be blank.

This occurs 100% of the time with any option.
