The answer
A zero balance can mean the wrong network or account is selected, the original wallet used a passphrase, or the new app derives a different address. The blockchain balance may still be at the original address.
What to do next
Compare the old public receiving address against one derived by the restored wallet. Check enabled networks, account indexes and the exact passphrase without exposing the seed.

Frequently asked questions
