Versa 4 Clip

[clarkbremer]

I found the post where the Fitbit moderator said not to use non-Fitbit products with the Versa 4. Replies were turned off on it so I could not ask this there.  Now, on the Fitbit store, there is a clip for the Versa 4.

But the following warning is posted with it: "Works with Sense 2 & Versa 4 only. Features will be limited while device is in clip due to covered back sensors."

Can anyone tell me which specific features will not work while in the clip?

@clarkbremer , Thank you for your message. I'm glad to see your interest in the Clip for the Versa 4. 

The features that might be affected using the clip are mostly all the features related to the heart rate. 
As you will be wearing the Versa 4 on the clip, you won't have any heart rate readings.

@clarkbremerif you look at the specs of the Versa 4, anything that needs the pebble portion to be in a clip - heart rate, skin temperature, oxygen sensor.
