Student phone locked after exiting exam mode
I have a student who was using the 3D calculator in exam mode on her iPhone XR. She was able to exit exam mode, which put her back on the regular (purple) 3D calculator, but she cannot exit the geogebra app and she is unable to restart her phone. In particular, she is disconnected from wifi and her phone is in airplane mode, so she's also unable to access the help. How can she exit the app?
