When working at home or at a remote location, we do not take timings seriously. What happens is that each one in the team starts to work at their own timing taking mostly family into account and chores to do and just being lethargic in the morning. We get into the mode of saying if I eventually put in 8 hours that would be enough.
The truth is this destroys the rhythm of the team. One might be a morning person, another a night person, another likes to work in bursts and so on. This makes people waiting on each other endless and delays tasks getting done leading to frustration and doubts if the person is actually working.
Set a timing for the team, connect over a group conversation where everyone checks in and then work through the day being connected with each other and then break off at a set time.
