All data disappeared on active Anki Account

I’ve recently got a new laptop and have downloaded Anki onto it. I have signed in to my account and there is nothing there, blank account with no flashcards. I’ve also logged on to my account on ankiweb and it’s blank there too.

I was regularly using my account so wouldn’t be because of deletion, and I definately had an ankiweb account that was being synced as a similar thing has happened before but I luckily had access to my local files on my old laptop then asn was able to go back and ensure everything is synced and uploaded. My old laptop is unaccessible now so I can’t do that and I dont understand where my last 3 years of cards have gone. Help help help!

From the symptoms you described, it might be that you have 2 different AnkiWeb accounts. Please check to see whether this might be the case. If you previously used one account on your old laptop and are now logging into a different, empty account on your new laptop, that would explain why your collection isn’t there.

When you started using Anki on your new laptop, were you asked to perform a one-way sync and if so, did you choose the “Upload to AnkiWeb” option? Another possiblity might be that you performed a one-way sync and uploaded the empty collection on your new laptop up to AnkiWeb.
