If your token doesn't have any transactions in the past 24 hours you won't see it on the screener and you may not be able to find it on the search screen.

Once the token has a transaction again within the last 24 hours window you should be able to see it on the screener and search screen.

The token is still being tracked and you can find it by visiting the token or pair URL: dexscreener.com/[chain]/[token or pair address]
