I just made two xmr deposits to Kraken, but after 30 confirmations they are not visible there. Have you experienced this kind of delay? How long will it take? The xmr deposit address is definitely valid.
Usually xmr has been visible after 15 confirmations.
Hello! Never had such problems, always brought everything through the monero and very quickly pass the transaction, most likely the problem with Kraken. Contact technical support.
