Yes! I am having this issue as well. I transferred miles on Tuesday 2/13 from CapOne, and it was instant, no problem, booked our outgoing flight. Perfect. Finally on Thursday 2/15 I had time to look at our return flight, and Avianca was still looking like the best deal, so I transferred miles that evening, and as of now, 48 hours later, nothing. No miles. No confirmation email. I called CapOne earlier, and they said it is not on their end and I needed to call Avianca. So I just now called Avianca. I did not have to wait long, but the customer service agent was not super helpful and said I have to wait 72 hours. So I am hoping to see the miles by tomorrow evening, and if not, I'll be calling back and asking them to escalate. (Tip: Use the Canadian number as the number listed for the United States has a recorded message that I unfortunately could not understand and then hangs up.)
