I just received my pocket today. After setting it up - which went completely fine - I updated the firmware.
Afterwards, I was unable to start the pocket again. I have been pressing and holding the button, having it in the charger (it was 90% full battery when I received it), but nothing seems to work. The LED doesn’t even flinch.
I can read that there are a lot of people who are having this issue. This is honestly not a great first impression on the product.
