Yes. Wells Fargo epically failed at how to run a datacenter and it has been revealed they have improper fall-back/backup procedures and systems in place.
The issue with RW and WF short codes, as far as I understand it, is ENTIRELY a Wells Fargo issue, not at all anything to due with RW. I have been told by some friends and contacts of mine, who are not on RW, but are with a major carrier, that they can not get the text codes or calls either.
I truly do hope Wells Fargo will resolve the issue. But for me, I have changed banks. And I strongly advise everyone do the same.
