I have the same problem to: freezing, especially if the search field is not cleared after previously using the app. Force killing the app from the iOS app switcher is the only way I’ve found to resolve it. This happened on my last iPhone (iPhone 8) and still happens on my new iPhone (XS) and my 11” iPad Pro. I’ve tried reinstalling / redownloading offline notebooks. Nothing fixes it. I’m reaching the end of my patience with Evernote. Ive been a paid user for years and have slowly seen the price go up and the bloatware go up while the core functionality and stability has gone down.
