The Incomm rep told me today that they believe they've fixed all of the cards with issues. The CVS issue was nationwide, and I believe was limited to Saturday Dec 8 only.
Not sure if it's really nationwide or I was lucky. I purchased 2 VRs from CVS on Sat morning (Chicagoland area), then purchased one more at a CVS in central IL around dinner time. And successfully loaded all 3 around 10-11pm that night. No problem at all.
