Huawei Mate 20 Pro Android 10 update?

Apparently Android 10 is already out for the Mate20pro. The HiCare app says that it can be downloaded from the app under System Update. For me it doesn't work but friends of mine already have it. Does anyone have any idea why?

Because updates at Huawei are delivered in waves. Means your friends can have it now, but you can only have it in 4 or even 8 weeks.

What kind of build number do you have?

Do you find under Settings and then I believe under System.
