A:AnswerI use a 128 GB USB (not FAT32) and everything works no problem with VLC. The built in app is OK but VLC is better and free. Maybe the projector OS has been updated?
A:AnswerHello. I've seen the message for updating the projector, and I am able to continue using the proyector while that is happening. Note that I mainly use an Amazon firestick rather than the projector apps. Still, while it is updating, I can switch inputs as normal and I just see a message stating "update in progress". Your situation doesn't seem normal. I would contact Epson's tech support if it is still under warranty.
