Hi
What is the recommended way of resolving conflict in the iOS app? On desktop I use the Joplin plugin to resolve conflicts, but plugins aren't available on iOS (I think?)
You are right, plugins won't help. If you have a good version of your Joplin profile on your desktop, erase the Joplin app from your iOS device, and start all over.
That would just lose the local changes I wrote on my phone 
I want to know how to merge, not lose everything!
How many changes have you made on your phone (new notes, changed notes) BEFORE this problem started ?
I often multitask between my phone and my desktop computer. So I regularly get conflicted notes in Joplin. Maybe every 1-2 weeks? On desktop, I use the Joplin module to resolve the conflicts. But on iOS, it's unclear what I'm supposed to do to resolve the conflict. The app offer no guidance, no hint.
How do I resolve a conflict?
Anyone has advices on how to merge conflicts in the iOS app?
Try these conflict resolution instructions which should work for either Android or iOS.
Note: viewing a note in the Conflicts folder shows that it's in a different folder. It's not and you still have to move it to a different notebook.
These instructions can also help when the Conflicts notebook doesn't appear on desktop, as described in my thread: Notes created in Android Conflicts notebook don't stay there
With how Joplin sync works, I tend to multitask on mobile by creating new notes, syncing them, and then merging them into existing notes on desktop.
This helps prevent conflicts and can encourage discarding the Conflicts notes and notebook (in that order) over cumbersome conflict resolution.
That process is quite complicated. And not covered in the user manual?
So normal users are just expected to guess how to proceed?
