Android Oreo update 8.1.0 fixes bluetooth issue with OW+
I'm part of the Android Beta program. Installed 8.1.0 yesterday on my non-rooted Nexus 6P. Turned on my OW+ and the Onewheel App on my phone was able to quickly connect and connect to the board.
Another user on the FB Oweners' Group page confirmed this, but said he still couldn't connect to his OW v1.
