Adding on to this, other things i've tested:
Resetting xcode, my mac (m1 macbook pro), my phone.
Removing and re-inserting sim card, calling wireless carrier to ensure that I'm in good standing (and thus not somehow "offline")
removing and re-installing the development app
validating the device token using the "tools" provided through the CloudKit Push Notification Console (i have the correct certificates w/the correct device token, etc)
turning off -> on developer mode on my phone
