That being said I've since learned that ColdCard policy states that they don't make customers send their devices back, so I'll just wait for the new one to arrive and just restore my backup to it. No need to move my BTC anywhere.
That's even better, and it's a good policy. It's safer for the end-user than being forced to send the hardware wallet back, not knowing who will look at it and what could happen. Your problem occurred on Friday. It's now evening hours on Monday. Did someone reply to you from Coldcard's support and what did they say?
