I've been trying to send my XRP from my Coinbase account to my nephew's Coinbase account for the past 3 days. Every attempt to do so has failed. They even disabled sends for 24 hours for "my security".

I tried again this morning, after the 24-hour ban, and I continue to get the following error message in my email:

Your attempt to send 23.1243 XRP was unsuccessful. Your funds are safe and have been returned to your XRP balance. You can try sending again below. Reason: Network or other technical issue.

When I "try sending again", the same thing happens. So, at this point, I'm done messing around with it because I don't want another 24-hour ban.

Anyone know what's going on?

FYI: I'm sending the crypto from my desktop (Windows) to my nephew's iphone. I sent only a small amount of XRP as a test.
