Instinct Tactical Freeze

Hi

When I use the function "follow me" the watch freeze after approximately 30 sec, then I have to restart it. 

But I see it when I come home, the watch still shows the time when I left the house, but I'm been out for like 1 hour.

The last 2 times I used the function it happens, but worked fine before, I tried find out which is the latest version, I have: v.18.54.

I don't know if it's have to do in combination with autolock?

Anyone had this issue?
