However, every few weeks the official Obsidian sync makes an absolute mess of our shopping list (which has fairly frequent edits and deletions across our laptops and phones). I have no idea how to fix it.
This thread shows other users having the exact same issue as us: https://forum.obsidian.md/t/obsidian-sync-incorrectly-duplic...
If it wasn't for this one issue I would be able to strongly recommend the tool but as it is now I just tell people it sort of works and I am mildly happy.
To be fair I don't think any of the popular alternatives like logseq or joplin even attempt to do automatic file merges and just dump files into a conflict mode.
