As of a week or two ago, my SMS alerts from FlightAware no longer include expected routing. This was a key feature to me as it allowed me to anticipate my clearances, lookup unfamiliar identifiers, etc. before calling ATC for my clearance. (Perhaps related, the number of SMS messages constituting the notification decreased from two to one.)
The routing still appears in my notification email, but that’s not as accessible to me as a text message.
I hope you can undo this change.
