I've had this issue too where my mount would appear after a short while and I believe it may be connected to map loading. For me, my connection is slower than most (mobile phone connection) and I can and usually do sit and watch my map load up while at a waypoint. If I get on my mount as soon as I waypoint, as soon as the map is fully loaded my mount appears. If this is true for everyone, they shouldn't tie mount loading to map loading. They should tie it to character loading since your character loads immediately. It's only right in my opinion.
