I've recently updated from Reaper 5 to 6 (but still very much a newb).
I'm using a NanoKontrol 2 studio using the keymaps described in this thread:

Everything works as expected including the mute and solo hardware buttons but the mute and solo indicators in the MCP don't switch on or off as expected.
I can't remember whether this was working previously in Reaper 5 so not sure if it's a known issue with the hardware/keymap or a bug in Reaper 6.
Has anybody else seen this before?
