Nextcloud can't even get Notes done right. I lost the entire contents of the note randomly not long ago. And the mobile Note app refuses to load the editor sometimes.
That being said, most of the time, Nextcloud works ok. I don't want to replace Nextcloud with another jack of all trades, master of none. Instead, I'm slowly migrating to good alternatives that do one thing well: Immich for photos, Obsidian for notes.
