I play on a Realm but did not notice mob loss until after 1.17. It seemed like there was the major 1.17 update then a smaller one a weekish later. The mass elimination of mobs seemed to accelerate after that second update.
Complicating my complaint is that I invited a second player to my realm around the same time. So if logging in and out can despawn mobs, then perhaps they helped encourage the slaughter.
