Powertap G3 Hub not waking up

Hey guys,
I tried PowerTap customer support twice but they are unable to help me.
I have a G3 hub and it’s upgraded to the last firmware version 16.xxx.58 (I’ve confirmed it also in my garmin edge on sensor details> about).
It refuses to wake up after you spin the wheel.
To wake up you have to open the hub remove the cap, remove the battery, wait 1 min and put it back on.
Imagine doing this on every 7 eleven/cafe stop… Jesus!

I’m out of options, don’t know what else to do. Besides fix this problem, sell this thing and buy a Quarq, SRM or Stages.
Tried the search function here on the forum. The official powertap thread is abandoned by the company.
Also tried searching the web, but to no avail.
Also thought it was a battery problem, so I exchanged it 3 times already (bought some expensive duracell 2032 3V). Nothing…

Appreciate all the help, comments and suggestions.

just had a slightly different problem but ill bet the solution is the same. mine wouldnt send the signal to my garmin. i ended up buying a joule to confirm it wasnt the garmin. cost me $100 of my own money to solve a problem. neither powertap nor garmin would admit it was their problem till i got one guy at powertap on the phone who immediately said ‘its the cap…its not sending the signal to the garmin’…his logic was that the hub was fine since i could upload the firmware…call them and ask for a new cap at least…
