Had the exact same thoughts.

* I thought at first they meant "later" was too vague, but omitting the word only makes the message more terse, not more specific. It's as if they decided ahead of time that the old message was bad and embodies certain qualities (which they highlighted) and the new was good and embodies certain other qualities (also highlighted), and they didn't bother to rethink the new one after seeing almost the same phrase used as examples of bad and good.

* "Your changes were saved": yeah, if the change is connecting your account to a third-party service, and they were unable to connect...did they save the intent to connect? How do you resume it? Or was this part of a greater set of changes? The reassurance works best if it's consistently true, but I'm doubtful.
