I get really bad pre-cue drift about 30 minutes into a set with Harmony H224 interface

Hi

I’m using the HARMONY H224 by Serling as an interface for pre-cueing.
About 30 minutes into a set the pre-cue and main channels are very out of sync, almost by a full count.
It is connected through USB-C.
I’ve tried on Intel and M2 Macs - same result.
The only fix is to disconnect the interface, reconnect and reassign pre-cue channels, which causes skip in all the audio.

Please help I have a gig on Saturday!

@Aaron_DeYonker have you tried turning Bluetooth OFF on your Mac?
