BC127/ Melody 6.1.3 TWS issue

I recently upgraded Melody to 6.1.3 from 6.0.53, and my TWS has stopped working!

It all seems OK, and opens the TWS port fine, but even using a terminal, once you start to stream aptx material the BC127 just reboots, and all links are lost. I have replicated this over 5 devices, so I’m pretty sure it’s not my hardware. Reverting to 6.0.53 solves the problem
Any ideas?

Just solved it: 6.1.3 requires that there is at least one AVRCP profile in order to work with TWS. Bit of a pain, but once added it works properly.
