[Apple Watch] The complication is not updating
The Cardiogram companion app for the Apple Watch requires WatchOS 6.2. and above. If you no longer see the app on your Apple Watch, please be sure to download the latest version of WatchOS. - How To Update your Apple Watch
The complication should update every 15 - 30 minutes (and more frequently -- every 5 minutes -- if the Cardiogram app is open in the background on the iPhone). If this is not happening, try restarting your watch. To do this, hold the side button for a few seconds ( not the digital crown), and slide the power off button to the left on the screen. This will turn off the watch. To start it again, hold the side button. Restarting your Apple Watch usually fixes any complication issues.
Some complications may not be fully compatible with the Cardiogram complication.
We have designed Cardiogram to continuously send as many updates as possible so you can stay updated on the go. Apple has limitations on how many times a third-party app can send updates to an Apple Watch. For further information, please see this document under "Transfer Data from iOS."
