LED no longer turns off

It appears both my RPI4s have received an update (not Ropieee - they were already on 4.002 and I’m not on the beta channel) that has caused the red LED to stay on despite the setting being ‘off’ in ‘advanced’. Both are displaying the same behaviour and the LED occasionally blinks (every 4-5 minutes). I’ve tried a different setting and reverted/rebooted with no luck.

Many thanks.

This may well be due to an indication of low supply voltage incidents, reseat your USB power connectors a couple times…

Thanks. Has resolved itself on both units.
