Apple Watch GPS (Apple Watch series 2)

This is the most strange phenomenon in Apple products! I am one of the most loyal customer to all apple product and after 3 months chatting with customer services and senior and top senior advisor still they are not able to resolve my Apple Watch GPS issue! So annoying...!!!

My GPS is not working properly and it will be on and off working (I meant without connecting to the phone).

Am regular runner and swimmer and cyclist and this simple issue is become a major in my life.

Tried keep calling customer services, raised more than 10 tickets and loads of time spending and changing my watch once to another one! Still same issue, same problem , some days all GPS functioning amazingly well and some days change to motion only (same Apple Watch series 1).

Strongly not recommended this Watch until this is going to resolve ... so much disappointed as customer service not helped me to resolve this issue within this period.
