I am still struggling with this issue of getting into an endless crash loop on iOS due to an embedded PDF file (the note loads fine on other platforms), that I first reported here: Obsiidian in a crash loop on iPhone
I’d like to suggest that if Obsidian crashes and restarts, that on restart it does not attempt to reopen any notes until the user selects one. That would be much more robust than the current behavior which requires me to use the Files app to delete the note (and that’s assuming I know which note is causing the problem).
