United miles were the only redemption option and both had redeemed successfully previously so the MP # is correct. Contacted customer service, of course no response. So the data points for us are:

United miles - mixed results. If successful, takes 5 days, or will show FAILED (Redeposit back to e-miles account in ~11 days)
Starbucks gc - received successfully in 5 days
Amazon gc - received successfully in 7 days (updated)

So if I had to redeem e-miles for United as my only option, I would open the E-rewards account and get the 1000 e-miles pts converted to $50 e-rewards which can be redeemed for 1000 United miles, same as e-miles, and hope for better customer service that e-miles.
