The 19.4 update in December 2019 changed a lot, especially with ILS approaches. I’ve linked a source by Trio that should help you figure out how to use APPR post-19.4. I’ve also linked a video that covers the new NAV settings. More information can be found in #tutorials. Hope it helps, and feel free to ask more questions if needed!
