I have recently gone from the fuze to the new fuze +, so far hugely disappointed. The older version was so much easier to use, very intuitive - the new fuze + is in a world of its own. The lock feature on my device is not working, and because this device is SO sensitive it’s a feature that is needed if you intend on breathing while you touch the device
Have you updated the firmware? The locking procedure was changed to the power button.
use the firmware update on the forum then all you need to do is hold thw power button for 1/2 second.
You can use the firmware update. I did it the other week…
