Hi, firstly Monica, I left you a PM last night, so please check.
I can't confirm or deny that Central time zone had an Amazon issue. I can say, I am in Pacific zone, and all went well at exactly 3am, because I was still awake and busy on PC when saw my devices had all changed from 1:59 am to 3am immediately; my cell phone, computer clock, and Alexa devices were all on the money. (My atomic clocks have issues I have not adjusted recently, so they still have them. Bad reception with atomic clock's mother ship in Colorado, but that is another story I can fix.)
It is a fact that people who did not have their location at US and time zone correct in their Alexa devices did get slammed. We heard from some today here, as there were quite a few separate posts (and confessions) this morning.
