Balance is always zero

[empav]

Hi there, I'm not sure if it's a bug or because of my technical debt. This is my wallet:

on 2 networks, mainnet and sepolia for tests. I can switch between the 2:

Balance is awalys 0 but when I try to "Send" I get the exact number of eth and stuff that I do have in my wallet:

Also I'm trying to fetch the balance like this:
const { fetchBalance } = useAppKitBalance();
and later on accessing the data like this:
Balance: {balance.data?.formatted} {balance.data?.symbol}

This one show up the symbol but not the balance.
Could anyone please help me out on this? Thanks.
