It turns out that there is a problem that the weather application of iPhone does not display '69 degrees'
It turns out that some versions of the weather app on iOS don't show up at 69 degrees Fahrenheit (20 degrees Celsius). A former Apple developer said, 'The iPhone uses temperature data in degrees Celsius, and when converting that temperature to Fahrenheit, the fractions are rounded, which may result in skipping 69 degrees Fahrenheit.' I'm guessing.

Some iOS versions mysteriously refuse to show '69' as the temperature in the iPhone Weather app ―― 9to5Mac

On July 13, 2021, the IT news site The Verge used iOS 14.6 and earlier versions of the weather app, and the temperature in Fahrenheit was 68 degrees, then 70 degrees, and 69 degrees. I reported that a problem was found that was not marked as. Below is an image showing the problem, where the iOS 15 iPhone (left) says 69 degrees, while the iOS 14.6 (right) has a temperature of 70 degrees in the same place.

We don't know exactly which version will cause this bug, but we know that iOS 11.2.1 didn't see this bug. Also, if you install the weather application as a widget on the home screen, or with the Dark Sky application that Apple acquired in 2020, it will be displayed as 69 degrees without problems.
Former Apple developer João Pavão said, 'The weather app internally handles temperature data in Celsius as an integer, and when displaying Fahrenheit, it converts from Celsius to Fahrenheit and then rounds off. In this case, some temperatures will never be displayed, 'he posted on Twitter. For example, 20 degrees Celsius becomes 68 degrees Fahrenheit, 21 degrees Celsius becomes 69.8 degrees Fahrenheit and is rounded up to 70 degrees, so 69 degrees is skipped, Pavão thinks.
Here's another hypothesis:

The weather app actually always uses temperature data in whole number Celsius degrees internally, and then converts to rounded Fahrenheit just for the UI.
You will never see any numbers that don't result from this conversion. Https://t.co/JdOrnivkua pic.twitter.com/SvdtBDJEjU
'I don't know if this bug is a bug or if it's a deliberate move to get rid of the net meme associated with the number 69,' said The Verge. Meanwhile, 9to5Mac, a news site specializing in Apple products, said, 'The widget shows 69 degrees, so it's probably an unintentional bug.'
