Apon updates, all non-system apps disappear while still being on the phone as well as the background changes to default
so as you might know that updates are common on lineageOS but a problem that pops up is as soon you update all the apps disappear while still being installed on the phone same for background turning to default. This isn't much of a problem for security or performance but it does make the OS look buggy and not user-friendly; the users see this and automatically think "this is a pretty buggy OS, I would rather stay on google's android and get all of my data just sold from me".
