The ATV4K has a lot more issues than that, but in the case of audio sync, when it's dealing with DolbyVision content on, say, Disney+ or Netflix, a lot of people, including me, have had to insert between 80 and 140 ms. of delay in the AVR's audio (in my case a Denon 4300) to compensate for how long the ATV4K takes to deal with DV.
And as you mentioned, several YEARS in, and they haven't bothered to fix their pathetic handling of actual 24 frame content. People surmise it's because they don't care, but with the large number of complaints I see, I think it's more likely they have no idea how to fix it, or else the poorly selected hardware they used to build the box can't accommodate it.
Having said that, and having owned various Roku and Amazon devices, I can say that the ATV4K is the best of a mediocre bunch of streamers when it comes to supporting high end formats like DV and Atmos. Their output from Disney+ content is really quite excellent, for example, with a ton of the content supporting both DV and Atmos properly.
