After I clicked to "attach", adress was attached. Then (after I saw, "adress attached") I made an transfer from another wallet to my newly created adress (that I attached). But I did that transfer before the attachment (bundle) was confirmed. The transfer is already confirmed, but I cannot see it on the wallet.
Should I rebroadcast the unconfirmed (for 2 hours) bundle?
The addresses do not need to be confirmed. But coin transactions do need to be confirmed. When you do a coin transaction it will show up in the History of your both sending and receiving wallets even if it has not been confirmed yet. It will show as pending when not confirmed. Can you see you coin transaction in the sending and receiving wallets? Make sure you log in with the correct passwords. If a coin transaction is pending for more than 30 minutes, you can do the reattach once every 30 minutes till getting confirmed. Don't do the rebroadcast which does not work for this situation.
