Works perfectly! My communication problems with my USB-C phone have been solved!
My connection issues have been resolved and seem to be working fine. A bit long and doesn't match the controller ports suggesting it's primarily for a tablet, but other than that it works great.
Pros
βFunctionβ Connect DJI Mavic PRO/DJI SPARK Remote Controller to most Type-C mobile devices (New iPad Pro 11 not included). The tablet may not support other devices.
