LG Urban 2 EU with IPhone - BT headset issue

[felek73]

I'm trying to use LG U2 with my IPhone 6s and BT headset (Plantronics M55) simultanously.
But after a few minutes/seconds of phone call conversation the sound in BT headset starts to mute - I can't hear anything and other party is also unable to hear me. After few seconds audio is back and again dissappears after a while.
I wonder if anyone has any expierence with such a combo - IPhone + BT headset with this watch.
If I pair my watch to android device (Moto X Style) there is no problem with using BT headset at the same time.

Make sure in Blutooth settings that "Play phone audio on watch"is not enabled.

There is no such a setting on the watch when it is connected with IPhone , it is present when conencted with android phone
