Well well well! I have to click on the greyed-out Settings button where it demands that I link my SiriusXM account. But at the bottom, as you reported, I can enable the free streaming until May 15th and I now see this (on alexa.amazon.com):
SiriusXM has been successfully linked.
What to do next:
- Try saying: “Alexa, play Howard 100 on SiriusXM”
- Close this window to return to the skill page.
