HELP! Collection Disappeared

My entire collection is gone. I happen to have had the website pulled up on my phone browser so I can still see all the cards I’m supposed to have, but when I look at the website on my laptop, there’s zero cards. Is there any way I can backup or export the collection from the mobile browser version so I don’t have to input everything again?

Resolved: I was able to request the desktop version of the website on mobile and export my collection from there.
