Whats the longest wait you've had for a transfer to go through. I used shapeshift late last night and it still hasn't come through. I just did another one and it went right through.
The longest time I ever waited for a transaction to get completed was 2 hours. Never gone past that. However, since you said you made use of shapeshift, have you tried contacting them since it is already a day and the new one you just did went right through. There could be some mix up somewhere. However, if there is a challenge, there is a possibility of it coming back to the sending wallet.
