It still keeps freezing in my case. Specifically, if I do a search from within a specific notebook, rather than the general search, and leave the search string in the search field, the App inevitably freezes when re-opened.
I'm a yet another victim of the bug. I have several notes which rely heavily on indentation, which stopped opening in the iOS clients of Evernote (work everywhere else).
Before coming here I'd created a copy of one of the notes and removed all the formatting. Surely enough, it opened on iOS without any problems.
Unfortunately I need the indents - otherwise the notes would become nearly illegible and definitely unusable. Guess I'll have to move these to Apple Notes until the fix arrives.
