Kindle Books not working for second account

[JackieTreehorn]

So I tried Kindle Books text-to-speech for my account today and it worked great.
But when we tried it for the other family account we have, we kept getting the
"Something went wrong" message. All the other Echo features seem to be
working fine for both accounts.

Is anyone else having similar problems? Any ideas on how to fix it?

Okay, it is working on the second account now. I guess it just takes a little time
to propagate throughout the system.
