As reported last week, an update to the My Disney Experience app for Walt Disney World had removed the ability to modify dining reservations, but today, a new update for both Apple and Android has been released to fix the issue. To once again modify any reservations, you must update to the newest iOS version marked version 4.19 Build: 20190205.1 or, for Android, version 4.19 Build: 20190208.1.
With the update, guests can once again modify a reservation via the app up to 30 minutes before the reservation or move the reservation to another available date and time and adjust party size based on availability.
No word was given from Disney when the app ceased this ability nor have we heard word now that it is back. We have also had both iOS and Android users test the update with success from both.
