Hi there -
Many thanks for your message.
Generally same day / next day morning checks are completed by 10am each morning, and Prime Time checks are done by 5.30/6pm at the latest.
At the moment, the team are finding there can be quite a lot of changes with the schedule each morning due to Covid-19 so to be conservative I would probably suggest updating around 11am.
Have a lovely evening,
Tiphanee
