I'm a.but stuck

I have created a parental control and added two devices to it

I set the bedtime mode to stop those devices being used until 7.30am

However, the devices still can't be used even after 7.30, as bedtime mode appears to be stuck "on" until I turn it off the next day

I have set the time to UK time in both the app, and on the web portal, but it is still happening

Any other ideas?
