Wallet shows empty (!)

I see Zero balances and Error messages when I open my O3 app.
I am very worried, since it s about a big number of NEO and GAS.
How can I access my coins ?

It’s normal now?
sometimes the unstable network may cause this issue, but don’t worry, your assets are stored on the blockchain, instead of the wallet. that’s how a decentralized wallet works. So always make sure you have already backed up your private key, then your assets won’t lose.
