Ionic timer not able to set digits

[hilfordjames]

Went to use the Countdown Timer today (fitbit developer) and cant set or adjust the digits, they're simply blank. 

When I swipe up and down the watch vibrates as if the digits are changing but they're not visible. 

When I go to the stop watch timer part of the app, it will show the milli seconds counting up but not the main numbers.

It’s good to see you in the community, @hilfordjames.

Thanks for the details shared in your post. I appreciate your efforts and recommend trying the following:

1. Restart the device: How do I restart my Fitbit device?
2. Switch to a Fitbit clock face: How do I change the clock face on my Fitbit device?

Hope this helps.
