Also, as the developer of Lemmios, it is somewhat negligence on my part (not saying this is true for any of the other app developers, just me), we all google when we code and generally the newer features make things much easier so it is really hard to google older features since they are harder to implement and get quite buried. I also think for me at least my apps start as passion projects I don’t really expect anyone to use so I forget that iOS versions under my current one exist lol, it’s a lot easier to start on 16.0 and stay on 16.0 forever than go lower after the project has started, sorry.
I think the reasoning was that there was a race condition between the code causing the bluescreen and the code updating to avoid the bluescreen so rebooting 15 times would give a lot of opportunities for the updater to win the race.
