Additional microphones CPW90 don't work when connected via Bluetooth

[System State IT_Support]

Experiencing the same issue
Waiting for an update from my distributor - they said that the CPW90 uses a DECT connection, so it's not an issue with only one bluetooth device connected at a time.
I'll try to remember to post an update if I get a fix

---

Apparently this is just not supported by the CP960 due to lack of power availability to drive both bluetooth and dect connections at the same time (that's what I was told anyway).
I told my distributor that Yealink needs to make a clear warning that this is the case, as it is not documented anywhere
