This has happened twice now. I do my practice questions on Uworld, log out (to do other things), log back in to do more questions, and I get a white Uworld screen. I have logged out, shut down, and restarted my computer. I sent a message to the platform but has anyone else had this issue? This is frustrating as I am scheduled to take the NCLEX next week and I didn't anticipate having any issues with this platform since it comes highly recommended.
