Sorry.

Understandable.  I’m a little overworked right now, or I would do some more research on my part to see if I could discover exactly where the breakage occurred.   Right now 18.06.8 appears to function on both the RB532 and the RB532A.  However I’m not using them for anything useful, they are just a couple of the many devices I have collected.
