I know that. It's my problem too. All I say - You have yo wait until official Global Dev ROM will be released. And good for You and me - it was released yesterday. Now wait for proper eu Rom.
It impossible to turn on Google Location History in MIUI 10. Option is inactive. Tried external tools (location history enabler) - no result.Tried to change region - surprise, this option completely disappeared.
