Charge 5 not vibrating during interval training

[TraceSPN]

My Charge 5 will not vibrate for Interval training.

I’ve read through the Forums and done everything suggested in the previous posts, but nothing has worked. I’ve restarted it, etc. I have tried the countdown to make sure the vibration is working and it is.  I’ve also gone into the app and set voice cues during exercise but that’s not working either. 

Is there another model that actually works with interval training and can I return mine because it’s not working properly? 

Is there anything else I can try to make it work?
