I'm trying to send IOTAs from Binance to my IOTA wallet 2.5.6.

I generated an address and copied it into the withdrawal section of Binance. Then I submitted and confirmed it in Binance.

When the Binance transaction history is said "processing" I hit the "attach to tangle" in my IOTA wallet. After some time I got a red "Invalid response" in the "attach to tangle" button.

The history in Binance still says processing. Have I done something wrong? Or do I have to wait until Binance has finished processing?
