An Apple support page is dedicated to address the latter heart rate.
The support page spells out possible problems not limited to tattoos.
Many factors can affect the performance of the Apple Watch heart rate sensor, the Apple page states.
Skin perfusion which explains how much blood flows through your skin is one factor.
Skin perfusion varies significantly from person to person and can also be impacted by the environment.
Uneven movements can also have an effect on readings from the heart rate sensor.
Last but not the least, Apple addresses tattoos.
Apples support pages, however, do not tackle the possible larger issue of alerts.
That issue has been making news on social media.
I wouldnt receive notifications.
Other commenters, who had the same kind of experiences, looked to back the claim.
The topic has also been trending on Twitter under the hashtag #tattoogate.
