Has this been resolved in Wikitude's new SDK and/or iOS 10?
Apple fixed the CMMotionManager issues in iOS 10.1 and later. Our Wikitude iOS SDK JS SDK already supports switching between gyro and accelerometer/compass since iOS 10.1 was released.
Which iOS and Wikitude SDK version are you using?
I'm using iOS 10.2 as my target and Wikitude SDK 6.0.0.
With our SDK 6.0.0 you shouldn't have any worse experience in geo ar worlds as with 5.x. Can you record and share some comparison videos so that I know about what we exactly talk about?
