Today I wanted to try GeoGebra Exams mode on my iPhone but when the last condition appeared ("do you want to start the exam" or something similar) I clicked "no". Apparently, as I had already accepted the app lockdown condition, I am unable to use my phone properly.
There is a grey line on the top of the screen, no timer and there is no "Exit from Exam mode option".
The only thing that is about Exam Mode is the bottom "Exam Mode" from the main menu, but when I click it, it doesn't show anything.
Please tell me what to do; I am stuck in flight mode and am unable to close or use normally my phone.
