Syncing issue between AnkiWeb and Mac

I’ve synced my anki desktop to ankiweb but the numbers aren’t the same. I’ve logged out and double checked that it’s the same account. I’ve forced sync one way from my desktop to ankiweb. It says sync has been completed but ankiweb still shows the wrong number of cards due.

Check if your Mac is using v3 schedule (2.1.45+)
in pc you can check in preferences > scheduling

Because the v3 scheduler uses a different approach to gathering and sorting cards, a v2 and v3 client may show a different number of due cards on a given day. While this will not cause scheduling problems, please bear it in mind if you’re switching back and forth.
