Now you need to work with someone in the UK. Can you talk to him right now? Who knows? You need to ask Internet about the time delay between where you live and where he lives.

In other words this has not changed either. So not a downside?

It is a downside, because with a time zone you know immediately if a time is suitable or not. For instance, if you see that in the uk is 4am, you know immediately that it isn’t suitable. If there isn’t a “standard”, you need to check every time if that time is suitable or not, and it isn’t as straightforward.

Integrated voice chat, or even better, Discord support like PS and Xbox are doing.
