Have experience working in teams up to 9 time zones apart, but not working at Zapier. I have phone set up to not disturb me with notifications between 10pm and 7am so I wouldn't mind as long as nobody expects a response before next working day morning. Before I could do that I simply did not have company's chat/email on my phone. My day starts with reviewing any received messages (no matter what channel -- email, chat...) and responding to them. I would find it unprofessional if someone did not. If this wasn't just an occasional oversight, then I would take it up with them.
