Having issues with all Hue filament bulbs since yesterday

Since yesterday morning all eight of my hue filament bulbs have issues. They are acting erratically, not going to full brightness, changing brightness or flickering. All other (30+) lights in my household are fine.

I can see that there was a software update on the 21st of July (1.122.8), so I believe it must be related to this.

Going through Philips support at the moment. Have tried resets etc, devices still misbehave even via Bluetooth.

Anybody else having issues?
