It still doesn't make sense why the app started silently downloading itself 3 days ago when I haven't had it installed in over a year. I do use iCloud drive but do not see anything related to the app inside of it.
Right, that's what confuses me the most. I was very surprised to find the reddit thread showing that other people are also having this specific app silently installed on their devices.
Yeah, I think the latter is more likely than the former. Perhaps a server side bug that's silently downloading the app on any device that's installed it previously?
Yes. In Settings > General > VPN & Device Management, it says 'Sign in to Work or School Account'. Is there a different device management setting that I should be looking at?
I would imagine that this isn't (or at least shouldn't be) possible based on Apple's security. The app is automatically downloading to my phone without my permission.
No, I've never downloaded it on my desktop. It appears that I downloaded it onto my phone over a year ago (I got an email in my inbox), but didn't want to pay for it so I deleted it.
