If coach is unavailable (absent or in meeting) immediately ask for another coach.

Right now, if a coach is unavailable (absent or in meeting), learners have to wait for 15 minutes before their request is put in the general queue. It would be nice if this didn't happen.

I feel the same.

It would be great to have coaches be able to mark themselves as unavailable temporarily
