Actually just did this myself last month. My team is colocated between India and the US, but I'm remote in the US to all of them. That's been the biggest challenge for me. I'm more of a visual person when delegating and encouraging. Very difficult to do that over messaging or email. Video conferencing helps, but not the same as actually being there in person. Had I known this was going to be the case, I probably would have postponed the promotion. But I'm going to stick it out and get through this because that's what I do.
