How does WatchOS refresh Watch complication data for myPWS?

The updating of complications (data elements displayed on the watch face) under watchOS is fully controlled by the operating system itself. Apps – including myPWS – can only request updates, but cannot directly control when or how often these updates are actually performed.

Apple optimizes update timing based on several factors, such as:

• remaining battery level of the Watch

• current system load and usage of other apps

• type of watch face in use (some are more restrictive)

• how frequently the user interacts with the app

• internal power-saving and prioritization mechanisms of watchOS

Important:

• myPWS can only suggest that watchOS refresh the complication at regular intervals.

• watchOS decides independently when updates are executed.

• A stable internet connection and enabled background refresh increase the likelihood of timely updates.

• A refresh of watch face complications will stop if the myPWS Watch App is terminated (killed) and no longer running in the background. To force a manual refresh of the complication data, simply open the myPWS Watch App.

Note on watchOS updates:

After major watchOS system updates, you may temporarily experience delayed or missing complication updates. This can happen due to internal system changes affecting background task scheduling or temporary re-indexing processes after an update. In most cases, this behavior resolves automatically after some time.

Note on Weather Underground data:

If there are problems or outages with the Weather Underground server, complications may be unable to update or refresh until the service becomes available again.

If complication data still fails to refresh, try the following steps:

1. Restart both your Apple Watch and the paired iPhone.

2. If the issue persists, remove all myPWS complications from your watch faces.

3. Delete the myPWS app completely — both from your iPhone and your Apple Watch.

4. Restart both devices again.

5. Reinstall the myPWS app on your iPhone.

6. Set up myPWS again and make sure to install the myPWS Watch App on your Apple Watch.

7. Reconfigure and add the desired myPWS complications back to your watch faces.

If you notice that complications update less frequently than expected, this is not an issue with the app itself, but rather a result of watchOS system policies or temporary data source limitations.
Apple prioritizes battery life and system stability, which can cause complication updates to occur less often or with some delay.
