Does the iOS app no longer support conflicting edits in notes?
I often have examples where I've edited a note on iOS but then closed my phone before the changes were saved to the server, then I forget the note is edited on iOS and I go and edit the same note on my Mac, which gets saved to the server. Next time I open up Evernote on iOS I notice the unsaved changes are marked as not synced to server, they get uploaded to the server, and then immediately overwritten with the version I had previously saved from my Mac. The changes to the note from the iOS app are lost (but can be found in the Evernote Premium note history).
Previously this would have caused a edit conflict to be marked either in the note, or the note moved to notebook of conflicting edits. However, now note conflicts just seem to get silently "resolved" by having the changes in the iOS note replaced by the server version.
At the very least I would expect that we should get a notification that this has happened even if there is no way of resolving the conflict (other than checking the Evernote Premium note history: which is not ideal if you don't have Premium), but I've never seen such a notification in recent years.
