Delayed Receipt of 2-factor Authentication Texts/Calls

[Gary-]

My phone is extremely delayed when receiving 2-factor authentication texts, which has been happening since I set up/connected my new Pixel Watch. Prior to this, I'd receive them pretty much instantly, but now they take up to 10 minutes (at which point they are no longer valid).  It's occurred with multiple websites: shopping, banking, insurance, and MyCRA. Other texts and calls come through no problem, as far as I can tell. 

 My phone SIM and my watch's eSIM appear to have been assigned different phone numbers in my account, so I'm wondering if that is affecting it somehow?

Easy device will have it’s own identifier (phone number), so as long as the 2FA is being sent to your phone’s number it should arrive as in the past. You could try turning off the watch and see if things change.

Have you tried @NFtoBC 's suggestion of turning the watch off to see if that speeds it up?
