I upgraded to the 10x version of EN on iOS, figuring I may as well learn the new version since I’m just beginning to do more with the app. But the offline issue is a real problem for me. I live in a rural area with NO broadband service. The only internet is via cellular hotspot, which has limited data. Without being online, I can’t see downloaded notes. I need to go back to the old iOS version, but can’t find it in the App Store. How do I go back?
