IPTV Smarters Pro lets you save more than one playlist or login as a separate profile inside the same app install, which is useful for a household sharing one device. Each profile keeps its own independent favorites list, with no overlap between them. If you switched profiles, added a second login, or simply picked the wrong saved entry from the profile screen, your favorites aren't missing at all, they're sitting under the profile you're not currently viewing. Open the profile switcher first, before assuming anything was lost. This is the single most overlooked cause because the app gives no warning banner when you land on an empty profile by mistake.

If a parental control PIN is set on the account, it can restrict which categories appear on the home screen without touching the underlying saved data at all. A locked favorites category looks visually identical to a genuinely empty one until you enter the PIN and unlock it again. Check your parental control settings inside the app before rebuilding anything or assuming the worst. This particular cause is easy to miss because nothing in the interface actually tells you a category is locked rather than empty, it simply doesn't render on the screen.

Like most player apps, IPTV Smarters Pro occasionally resets parts of its local storage during a version update, and favorites live inside that same local storage, not on a server tied to your account login. Check your device's app store for a recent update matching the timing of when favorites first disappeared. If the timing lines up closely, this is a one-time reset caused by that specific update rather than an ongoing fault in the app, and rebuilding the list once should reasonably hold until the next major version change arrives.

On Firestick and Android TV, clearing an app's storage, not just its cache, through device settings wipes its entire local database at once, which includes every saved profile, playlist, and favorite together. This can happen manually when you're troubleshooting something else, or as part of an automatic low-storage cleanup you never actually see happen in the background. If you or the device cleared storage recently, that explains a full wipe far better than assuming a bug in the app itself, and there's no partial recovery once storage is cleared this way.
