Reminds me of Apple Remote Desktop. It used to be an amazing application for managing our fleet of signage machines, an indispensable tool. Then (I think after Sierra was released), we started getting occasional crashes. It wasn't very often, but it was annoying. Then High Sierra rolled around, and it became unusable. You'd be lucky to go 2 minutes without a crash. And there was no consistency to it. We submitted bug reports, and nothing ever happened...until October 7 of this year, when I noticed an update queued in the App Store for ARD.

We had to abandon ARD so I don't know if they actually fixed it, but the price is still $80, and at no point has Apple ever lowered that price, even when it was unusable.
