Keyboard hypershift mapping says "requires razer synapse", which did work in Hyperspeed mode, but not in Bluetooth mode

Hi,

I’ve used Razer devices for some time, but this is the first time I’m playing with the hypershift function.

I’m running Synapse 4.0.86.2505070637, and the device in question is Deathstalker v2 Pro TKL, firmware 1.3.0.0.

The hyperspeed dongle is paired with the keyboard and an Orochi v2.

I mapped the hyper+wheel on the keyboard as displlay brightness, which did work when the keyboard is in hyperspeed mode. But this mapping does not work in Bluetooth mode, even when the Synapse is open.

Is this how it supposed to work? If not, what suggestions do you have to make it work?

Thanks!
