iPhone 14 activation "let's fix a glitch"

Ordered two 14 pros which arrived yesterday. Activation of the first phone (mine) went smoothly once I received the email from xfinity that it's time to activate, which arrived about 1 hour after the phone was delivered. Started working on setting up my wife's phone later in the day, well after we got the activation email. Feeling confident about my setup from earlier, I set hers up the same way I did mine - updated the old phone to iOS 16, then setup the new phone using the quick setup/transfer from old phone. No issues were encountered. Then I logged in to my xfinity mobile account > devices and launched the activation. A text message was delivered to the old phone with a confirmation code, which I entered and worked fine. Got the message that the activation was in process and an email would be delivered when it was complete. Told my wife to watch for a notification on the new phone about esim transfer and to accept. No notification came through. 30 minutes later I logged back into my devices page and I see the following message:

Looks like we ran into an issue with activating your device. Give us a call and we'll get it worked out."

I got on chat with support - this was around 8:20pm PT. Took a good 20 minutes to get through to someone at xfinity mobile, who went back and forth with me a bit before saying he was seeing the same issue on his end and need to consult with his team. Then he asked me ridiculous questions like "did you receive a SIM card" and started sending me links to various generic support articles like "what is an esim". Finally after about an hour, he says I have to wait 12-24 hours and that he created a case in their CRM for someone to resend the activation message. Really? There has to be a better solution here.

EDIT: it's 5:06am PDT right now, I tried calling the xfinity mobile support number but it says they are closed and to call back during normal business hours. Are they closed on Sunday?
