Updated to Philips Hue Pro - Broke Homey Pro Mini Zigbee

Recently installed a Hue Bridge Pro to replace my two older Hue Bridges and get everything in one place, Home Pro Mini Zigbee is very very poor now, not picking up devices when they were rock solid etc.

Philips Hue - I moved to Channel 15
Home Pro Mini is on Channel 25

Any insights as to what to do?

Are you certain the issue is caused by the Hue bridge and not by, for example, a recent Homey firmware upgrade?

Does your network start working properly again when you power off the Hue bridge?

It started in the evening of the day I installed the Hue Pro. So before the recent Homey firmware update.
I shall switch the Hue bridge off and see if things improve - might take a while though, lots of flows use the Hue bridge

Unplugged the Hue Pro bridge and things improved slightly.

Switched the Hue Pro back on and things have stabilised.
