If your newly set goal is not reflecting on your watch, there could be a synchronization issue between the app and the watch. Here are steps to troubleshoot and ensure your updated goals appear on your watch:

1. Ensure that the watch is connected to the app or not.

2. The watch and app may have automatic synchronization intervals. Give it some time to see if the updated goals reflect after a sync.

3. Close and open the page 'Daily activities' to see the updated goals.
