Unable to Check for Update

iPhone 14 Pro on iOS 16.5.1 (c)

First time seeing this. Got a notif that an update is available but keep getting the "Unable to Check for Update" message. Anyone else seeing this today (3-Aug-23)?

Tried on home wifi and at work.

Tried a hard reboot of phone.

120+ GB free.

Reckon Apple pulled a bad update that was causing problems?
