Question about Shokz OpenFit

Supports Multipoint (2 devices) according to the manufacturer. My older Shokz TREKZ Air also supported multipoint (2 devices), but if you moved out of range of one of the connected devices, an annoying acoustic signal was emitted. Has this been corrected in the meantime? In other words, can I now connect Apple Watch and iPhone in general and no longer receive the annoying acoustic signal when I leave the iPhone at home for outdoor sports? If so, does this now work for both OpenFit and OpenRun?
