I’m building a website using Next js that allows users to upload files to IPFS using web3.storage. I’ve followed their documentation (https://web3.storage/docs/w3up-client/)) thoroughly, and the account creation and file uploads are working correctly, and I’m receiving the CID as expected.

However, when I check the files on Web3.storage, they don’t appear.
I tried many times with different accounts on web3.storage but the problem is still there.
Note that I am using their free payment plan.

Could anyone please guide me on how to resolve this issue?
Thank you!
