I am a Microsoft sills4afrika scholar taking the az204 course, anytime I try to activate sandbox, i will be able to accept the terms and conditions but instead of taking me to the sandbox page, it return to the loading ( deactivating previous sand box, activating new sandbox, verifying permissions, creating file storage and so on) until eventually it says you have used up all your sandbox for today, come tomorrow, how can I successfully activate sand box. This is really stalling my learning, please help.
