@hoppy : Please can you confirm the model number of your Galaxy Watch? Also, what happens when you head to the Health Monitor app on the watch, and attempt to record an ECG?
In the meantime, please try restarting your watch and connected mobile phone to address any temporary issues that may have arisen following your recent update.
@hoppy : Please can you confirm if you are following the steps as laid out below when taking your ECG reading on your Watch5?
1) Open the Samsung Health Monitor app on your Galaxy Watch.
2) Make sure the Galaxy Watch is snug on your wrist.
3) Rest your forearms comfortably on a table and then rest a fingertip of the opposite hand lightly on the Galaxy Watch’s top button for 30 seconds. Remain still and do not talk while the Galaxy Watch takes the measurement. When the recording process has finished, the ECG results will appear on your watch. Note: Don't press the top button during recording; pressing the top button during recording will stop the recording.
4) Scroll up and down to see your ECG result. If you are experiencing symptoms, tap Add and on the Symptoms screen, scroll through the list and tap each symptom you are experiencing. Then tap Save to add the symptoms to your ECG report and to return to the Results screen.
5) Tap Done to go back to the Start screen. You can review your ECG report in the ECG Monitor app on your phone. (Note that syncing requires that the watch and phone are paired using Bluetooth.)
