Thanks for your reply. I know where to find the Archives, but I cannot see my collection inside it. There seems to be many archives inside, and having a look through it, i could not find mine. I also tried a CTRL+F search, but did not find it. Do you know why it could happen? Does the list not show all archives? How can I retrieve mine?
Have you tried to check "Metabase own DB", table "collection"? To verify that the collection is still there and see if it is archived or not?
Or if you know the collection id, you could check (through the API) its state (archived or not). To check through the API, you could try the following URL in your browser: https://metabase.xyz.com/api/collection/<collection_id>
where metabase.xyz.com is the URL of your metabase and <collection_id> is an integer value
Another thing you can do, through the API, is:
a) https://metabase.xyz.com/api/collection/. This will return a list of all collections and then you can search by collection name (ctrl + f), to find your collection
b) https://metabase.xyz.com/api/collection/?archived=true. This will return a list of all archived collections and again you can search by name.
If you find it, you can verify if the collection is archived or not and act accordingly.
