Unfortunately, we’ve just found an issue with Apple Watch steps: Apple Watch steps are not synced as today’s steps but will stack on the day you connect Apple Watch. We are working on an urgent fix at the moment but since developers are all on holiday so it might take longer than usual.
In the meanwhile, I strongly suggest to switch back to your old device. Please send me your short id so I can compensate for the switch.
Thank you for your patience and we’ll let you know as soon as the build is released.
