I am not able to set a profile seems they are busy up to today with DAI ( I hope that's the reason.) I used your reference and now I am stuck in this progress.

Some other info about NFT disappearing:

NFTs may disappear from your account due to token delisting or migration events affecting the specific NFT assets you held, or regional restrictions that may apply to your location.

Here are the steps you can take:

1. Check your email for any Coinbase announcements about token delistings or migrations

2. Review the Coinbase Markets announcements for updates on any assets you held

3. Verify your account settings to ensure your region is correctly set

Once you identify which specific assets are affected, you can understand the migration process and next steps.
