Recently went from a 6 on an older version of iOS (11ish? Pretty sure I had skipped 2-3 updates due to storage capacity being at its limit) to a 7 and updated to the latest version of iOS (12.2)

My employer has an app I use for checking my schedule, requesting time off, receiving news about the company, etc. on my old device I had to “allow enterprise apps” by going into Settings>General>Profiles.

How do I do this on iOS 12? The app icon migrated over when I restored my backup on the new device, but I can’t download it and I can’t find how to “allow enterprise apps” in settings. For one, there isn’t usually a “Profile” option under “General”. Except sometimes there is. It just either is there or it isn’t there but I can’t make rhyme or reason out of when it will be or won’t be. And when the option is there, it’s just a blank screen.

Any help would be appreciated. I can use a web version of the app for work, so at least I’m not completely locked out of a useful tool, but I liked being able to stayed logged in via the app whereas the website logs me out often.
