No Moto G4 Rear Camera Option?

Hello! As clear in the title, I have A Moto G4, and recently received the option to update my phone! I know that I would be constantly reminded to restart it, so I did. This is probably an easy problem to fix, but a day later a noticed there wasn't an option to use the user-facing camera. I then proceeded to check all my photo apps, and it continued with the same result. Any advice would be appreciated! :)
