Hi, I completed all the Training Station challenges and all 5 of the Earth challenges with 3 stars each, but I still don't see the Moon stages to continue practicing. How do I unlock the Moon and other planets in the Tello Edu app? I'm using the app on iOS12 and an iPad Air 2, I'm logged in with my iTunes account.

Well received Cis, since the Tello EDU app is provided by Wistron (Shanghai) Ltd. To reach the moon, we respectfully suggest you contact Wistron by dialing +86-21-64952384 or sending an email to stem_wsh@wistron.com.

Hi, I am also cannot reach moon. The I have the following message  "Access to Store Failed". No chance for me

Very frustrating!

I logged with my Google account and I have the same problem: Access to store failed.
How is it possible that it is no possible to go forward?
