We're doing a staged rollout. Current status available here: https://forum.k9mail.app/t/k-9-mail-is-back-5-800-release/1164/3 https://forum.k9mail.app/t/k-9-mail-is-back-5-800-release/11... Switching between the F-Droid version and the official APK (Google Play version) is not possible. You'll have to uninstall the old version first (and that will remove all settings). However, K-9 Mail supports settings import/export.
