DIAGNOSIS The thermostat and cloud server have a communication delay or conflict. Usually caused by a local override on the thermostat.
FIX On the thermostat, go to Menu > Schedule > Hold Settings. Set it to 'Follow Schedule'. This cancels any manual 'Hold' temperature set at the device. Then, in the app, force a refresh by pulling down on the main screen.
IF THAT DIDN'T WORK Re-link the thermostat to your account. In the app, remove the device. Then re-add it using the Setup Code found on the thermostat under Menu > Wi-Fi > About.
HEADS UP A 'Temporary Hold' set on the thermostat will override the schedule until the next scheduled change. Always use 'Run Schedule' to return to normal.
