I use MTGA when commuting and I need to switch to my bus or train ticket app when boarding. This causes the MTGA app to crash and restart. I am allowed to reconnect to the previous game after selecting the right format, but this does cause a big delay that can cost a turn or a forfeit if not fast enough. I also don't want my opponents getting the idea that I'm doing this on purpose. I think this should be looked at for a future patch for mobile as I am finding it to be a big issue and I assume others are dealing with this as well.
