the dumbest software bug you've personally encountered that somehow never got fixed

[Thomas75]

A calendar app I use daily has displayed the wrong day of the week for a specific recurring event for literally years now, reported it twice and it's still just quietly wrong

Curious what people's own version of this is, the genuinely small but persistent bug that's somehow survived multiple updates without ever getting properly addressed

weather apps I use has shown the wrong icon for rain for as long as I can remember, reported it once, got an automated response, and it's still wrong today
