Fortnite (a very popular online game) took the approach of simply not supporting any 1GB of ram iOS devices (so no iPhone 5s/6/6+, no iPad mini2/mini3/Air1). We’re going to try and keep supporting 1GB devices for quite some time - but it’ll be a constant battle when most Zwifters have 2,3,4,8 or even 16gb of ram. The game will keep getting bigger, but those iOS devices will stay what they are.
Anyway, we’re sorry for the issues - we are definitely aware and for the first time in weeks I can say we’ve made some real progress towards lessening the issue.
