Anyway, I'm sticking to K-9 5.600 with the original UX because the new one is very wrong for my use case: 3 separate accounts that must stay separate and a quick way to move between them. Given the comments on Google Play [1] and the old discussion on K-9 forums I know that I'm not alone.
I backed up the APK and sideload it on any new device I get, or after a full reset.
2003 maybe, but genuine advancements have been made since then that you probably want. Good luck trying to use the 2016 version of Figma/GDocs/[insert SaaS here] or even desktop software like Adobe CC or MS Office!
