Relax, your #helium miner isn't dead. Transitioning to #Solana means the network works slightly differently now; change is good!
In this case, you're no longer SEEING miner activity in the app, and in order to see your rewards you have to CLAIM them. Your miner is still working, you're still earning rewards. You may want to think about the implications of claiming rewards as far as keeping track of taxable events, or that may not apply to you.
In any event, the answer to "Miner ded?" is NO!
