So I got it working. I cleared the wallet of all sats for I had a zero balance, then I deleted the wallet and started fresh. After configuring my mints and enabling lightning in Settings, I did a test transfer to the new LN address, and it worked. The only thing I can think of is that I did something to screw up the LN address link to my Cashu wallet when I was first messing around with it and playing with different configurations and options. In any case, everything is working now, so you call this Case Closed! That's for helping me work through it.
