No GPS after update to SW version 27.14

After power on of the device the gps connection will be established for about 30 seconds. After the time the connestion to GPS is lost.

Result - ongoing and Neverending! message - "Acquiring Sattelites". 

For all GPS settings. for all weather conditions, all battery states! 

Reset doesn't help. Reset to factory condtions doesn't help. (downgrade software not dome, still waiting with some hope for bug fix :)

Is there any time line for bug fix this issue? It can't be so a big problem to fix it. 

Some SW regression testing could be helpfull for the development. This issue I had in last 10 years on more devices / many times!

I like some of the Garmin devices and I'm still wondering about such releases...
