iOS 15.0.1, Obsidian 1.0.4
In a note, edit mode (iPhone): Pull down for command palette > type in “sea” then press “Search current file” and the command palette just drops away and you are back in the note. Same for “Search & replace in current file”. Tried using the default theme and it’s the same, so not theme related.
In preview mode, Search current file and Search all files works as expected.
EDIT: I noticed the other day there was a pinned “mobile issues” post that listed search/find/replace as not working in edit mode. I can’t find it now in Safari(mac or iPhone) or the DiscourseHub app. Maybe someone can actually get the pinned “known issues” to stay at the top of the mobile section, then there won’t be so many posts about issues being worked on.
