Yaz pill. instruction that came with the pack allows to be up to 24 hours late when taking it. internet sources say - no more than 12. what to trust?

Create a routine: For the pill to work it needs to maintain a relatively stable level of hormone (pill med) in your blood. This prevents egg release. No egg= no pregnancy. Miss a pill= hormone level drops=egg released=risk. Take the pill at a regular time & this won't happen. Incorporate it in your morning or evening routine & it won't be forgotten. The less delay in a missed dose the less likely for failure.
