My Anki app was showing me different number of dues and new cards than my MacBook Anki was. So, I hit “synchronize” on the app and what happened was that the order changed on the app, like the files weren’t organized the way I had originally organized them, and the number of reviews cards and due cards changed but still does not match up with the desktop Anki.
This is making me so confused on which one it study and it’s stressing me out
