Cant see my btc in my wallet

hi , i cannot see my btc in the wallet in the bisq but in shows that is has been confirmed in bitlaps? and that i should have 0.02 bitcoin on my account
i sent it from external wallet coinbase

You should check the transaction id first in a block explorer to make sure that it is a problem with Bisq. Alternatively you can just check your Bisq address where you sent the coins to in a block explorer.
