Single post in Mass Evolving RTE Pokemon in Same Field

Please keep in mind that a *lot* of checks go into making evolution work. Putting multiple things into one "action" is already a daunting task (because if one goes wrong they all go wrong) and this is why for example the Berry Garden "fakes it" by just pressing the buttons for you one by one, allowing the server time to process them all. Interactions get away with it because there are a lot of shortcuts involved to make it work. Mass Move and Mass Release use similar shortcuts. Unfortunately there is no such shortcut for evolving because every species is unique. Maybe if it were limited to same species evolutions in a field, then it might be possible to shortcut it, but that's a very limiting restriction. I think realistically the best way is going to continue to be the Farm page. Keep in mind that on Desktop you can use the space bar or Enter key to hit the confirmation button (and Escape to cancel) to power through them faster.
