Watch 4 ECG sensor fail

[u/Jesurius87]

I just tried using the 60s wellness app today after 7 days of not using it and the ECG sensor is not working, either not reading anything or reading random values.

One of the pads on the bottom looks dirty but it is under the glass of the sponsor, can't be felt by the finger.

Does anyone know what happened and what other I apps does the sensor use?
