I'm using neon wallet and it is not displaying Neo balance or gas earned. Claim gas button displays unclaimed gas but does nothing when clicked.
I tried toggling the main/testnet but no result. Checked balance of public address and that looks correct. I am running 0.0.3
0.0.3 did not show any balance for me too. You can use their new version 0.0.5. It worked fine for me. The new version you can login using saved wallet or encrypted key as well. The link for new wallet is
