Most websites have an element that won't load on the first try, or a button that sometimes needs to be clicked twice because the first click did nothing.
Amazon shopping app needs two clicks every now and then, because the first one didn't do what it was supposed to do. Since 3+ years ago at least.
Spotify randomly stops syncing play status with its TV app. Been true for at least a year.
HBO app has subtitles for one of my shows out of sync and it has been for more than a year.
Games including AAA titles need few months post-release fixing before they stabilize and stop having things jerk themselves into the sky or something.
My robot vacuum app just hangs up forever once in a while and needs to be killed to work again, takes 10+ seconds after start to begin responding to taps, and it has been like that for over 2 years of owning the device.
Safari has had a bug when opening a new tab and typing "search term" too quickly, it opens URL http://search%20term instead of doing a Google search. 8 years ago I've opened a bug for that which was closed as a duplicate, and just recently experienced this bug again.
It really seems that criteria for "ready for production" is way lower now. If my first job 13+ years ago any QA noticed any of that above, the next version wouldn't be out until it is fixed. Today, if "Refresh" button or restarting the app fixes it, approved, green light, release it.
