Clock face won’t turn on and red/ green light on reverse

[Spinmistress]

Please help. Fitbit purchased at the end of November - not cheap at over 200e. Today it will vibrate if I click the left sensor but no clock face appears. If I swipe left - I can see settings but it won’t load. I also have green and red lights on the back. My old verse light half the price gave no problems. Has this been a foolish purchase. How do I fix?

Hi @Spinmistress - probably an issue with your chosen clock face.

In the Fitbit App select another clock face  and once loaded it would be a good idea to restart the watch How do I restart my Fitbit device?

@Spinmistress Green and red lights on the side the touches the skin is normal. They're part of the pulse and oxygenation monitoring.
