Open your Metamask wallet,
Check your address on snowtrace.io,
Look into the 'Activity' tab,
a) If there’s any outgoing transaction that was not made by you, we advise you to withdraw your remaining funds to another secured wallet address. It seems that you might have visited a fake site and your wallet is compromised. To prevent such things from happening, please, make sure that you’re accepting an authorization request from staking.step.app.
b) If there are no outgoing transactions, please, take these troubleshooting steps:
Unauthorize your wallet from the staking.step.app site,
Clear the browser cookies and cache for the staking.step.app site,
Authorize your Metamask wallet again and check the balance.
If there are still any issues with the staked balance, please make sure you connect the initial wallet that had staked tokens before.
After any mass issue — your balance will be updated when the issue is resolved.
