Yes, that's normal. The connection to GSPro from the MLM2PRO is through a third-party Bluetooth connector and isn't officially supported by Rapsodo. Hopefully, like other monitors have implemented, they will offer native support for GSPro in the future.
Great videos!! Keep it up
Is it normal that GS pro is still not available in the 3rd party apps?
