What are the problems that remote team has to face?

I think there are two problems, here is what we do to eliminate that. Productivity We believe in working fewer hours but being productive at that time. But recently we had to communicate with our team more than the normal, we use to schedule meetings and that meeting goes for around 4 hours or more than that and the discussion was not worth for that 4 hours. Maybe we are the only team, that facing this problem? Then, I tried to find out the best possible solution for this: If you're scheduling a weekly meeting for updates or progress tracking with your team then first circulate the to-do sheet or a sheet in which every team member right out the topics that need to be discussed. Then during the discussion, whenever the question is discussed just mark it as done. By this way, the meeting will be more productive. Communication We communicate for most of the time over slack channels and guess what!! we were spending 40% more time as compared through the call. We decided to explore more voice-based communication tool for remote team and we tried YAC and TALKIE. We were saving more than 40% of the time from before. Let me know the problems you're facing in your organisations, maybe anyone from this community can help.
