I have exactly the same issue - using Android too and the map never loads, always crashes. Was this resolved?

Confirmed for me too. This is really infuriating and has never been a problem for me previously. I've had a couple of horses killed by this now when I'm a large distance (through the Nether and Overworld) from anywhere with new horses to be tamed. It's a massive inconvenience and I would agree would be best improved by enabling passage through portals while mounted.
