For those who have been waiting for Pine64 to get the PineTime watches back in stock, they have them available now on their global store (https://pine64.com/product/pinetime-smartwatch-sealed/).
I have just ordered a few so I know I have the same watch as any new users who are trying to set it up.
Update: I ordered the watches on 02 June and they arrived on 20 June, so delivery to the UK is about 3 weeks.
The setup instructions (with some video demonstrations are here: https://openseizuredetector.github.io/pages-user/pine-time-installation.html)
