Download the ESS 3.0 system by JastroOne1 the same way you would download any other system (I also have the Juno+System downloaded). The ESS files download, but then the game crashes and won't work anymore. I am playing on an Android Moto Z2 Play. Unfortunately I do not have a screenshot, but I sent feedback a couple times when the app gave me the option too. Thank you!
@NathanMikeska yes! Thanks :)
