Inconsistent card counts when syncing

Since the last 2.0.82 Anki mobile update the iOS app doesn’t sync correctly.
Some cards done on the Mac and Ankiweb but are still to do on the iPhone.
To solve it I must :

  1. Rebuild on the Mac.
  2. Ask for a full sync Mac → AnkiWeb.
  3. Rebuild on the iPhone
  4. Sync on the iPhone who can detect (only after the rebuild process that Anki web has been reseted.
    After that everything works fine until the next day.
