How to recover card from Anki web

A couple of months ago Anki wasn’t working on my desktop so I used Anki web and made a hundred+ of flashcards.

Recently I started using Anki desktop again, and I’ve made a couple of cards. However due to a login error I had to re-login to my account. When syncing, I uploaded to Anki web, but I didn’t realize how long it had been since my account last synced, and I lost the hundred+ cards I made on Anki web earlier in the year.

Is there any way to undo this?

I don’t want to disappoint you, but I don’t think it is possible. Unless, @dae can do something for you.

If your account had not expired, it may be possible to restore it from a backup. Please post your AnkiWeb account on Private / Discussion Area - AnkiMobile/AnkiWeb Support
