PCM Wont turn on
Wanted to post this up to see if anyone has had this trouble yet. I'm scheduled for Porsche Dealer to take a look tomorrow and will share my results for others in future events.
PCM worked fine last night. I was on the phone through it when I turned the car off. This morning started the car and it wouldn't come on at all. I tried pressing several buttons, restarted the car several times even after driving. Checked fuses, all look good.
The car is a 2017 Cayman S with basic PCM (no CarPlay, no Connect) with 3k miles.
Dealer thinks it may just be a bad PCM. Luckily it's under warranty yet. If it's bad, I may try to get an upgraded PCM with CarPlay.
Any ideas???

Update: Dealer said the PCM was **** and they replaced under warranty. Had to spend an hour on the phone with XM idiots explaining and setting up new radio ID. So far working well!
Awesome experience as always with service staff at Porsche Irvine!

PCM reset worked for me. One point is you need to do this reset right after you see the radio resets on its own. Otherwise, while you are waiting for the hard reset, the reset caused by the bug might happen and you won't get the effect of doing the actual hard reset even though it looks that way.
