Visually impaired and seriously unhappy with the upgrade

I'm legally blind, and the new interface is nearly unusable for me. Just to see this as I type, I had to use header 2, and when using the app, I had to enlarge my device's screen size 3 notches, which has the effect of rendering the type everywhere else as ridiculously giant and discord's as just barely legible. (And don't tell me about the enlarge option in settings. It was set to max before the upgrade.)
