no not fee and amount so big that missing it more 2 btc and yes this wallet i use for long time
2BTC missing is definitely not fee issue, because the maximum standard transaction size at 10 sat/B wont reach that amount.
Can you remember the actual balance of that wallet since the last transaction that you've made?
'Coz there has been a lot of reported bugs in Blockchain's balance lately (
in Web Wallets child-board), mostly displaying previous balances.
And FYI, they haven't yet received any replies to their tickets.
I second the "
export solution", you just need to know that if you have more than one wallet in blockchain.com,
you'll have to create more than one wallet with different derivation path for the '2nd-3rd-more' accounts.
