When two addresses' explorer reports disagree on a token's decimals, the Send screen showed the stored figure while the confirmation screen said the balance was unknown. One function in send.js now gives both the balance and scale, so both read `unknown (SYMBOL)`. The confirmation screen's fee-unknown message names its cause: for an unknown scale it says the wallet does not know the token's decimal places and the transaction cannot be sent, instead of asking for a retry that cannot help. Other causes keep the old sentence. Model: opus-5-5
