I try to make connection with my OSMO with my Android (HUAWEI MATE 10)  but when I register the app is asking me to insert a CHINA MAINLAND telephone number?. But I'm from the Netherlands. I cannot change it. That's it. I'm out. Can't connect anymore just before a very important shooting!! Please help me out.

Hi, we're sorry to know about this situation. Have you tried to clean the app cache, then reinstall the app(latest version)? enable your DJI Go app's location to read permission from your phone setting, connect your phone/tab in very good internet situation. You may try to register into our website directly using your preferred email and password then sign-in on the DJI GO to see if that would help. You may consider using a different mobile device as well to isolate this matter as the Huawei Mate 10 hasn't been tested by our engineers. You may check the image below for our compatible devices on our Osmo.
