Issue with "Waiting for Schedule" several time a week.

Around November time I installed a smart plug that turns the Q box off on and on every 48 hours at 4am.

Not had to manually reboot the Q box or any of the minis since.  At the time I installed the schedule I  was rebooting the Q  about once a week

Eight weeks later and next Monday from 7pm is 'waiting for tv schedule' across all channels.

I have just had to have a replacement Sky Q box due to a HDD fail. I wait to see if I still get the Waiting for Schedule problem on this.
