Turn off LG Quick Start+ for a full TV restart test
Disable Quick Start+ temporarily if an app fault returns after normal standby. Use the menu path for the TV’s webOS version.

Use the correct menu for the TV generation
Quick Start+ lets supported LG TVs turn on faster after standby. LG publishes separate menu paths by model year and webOS version. Look up the matching path, record the current setting and turn the feature off. Shut down and restart the television, then launch the affected app from its own menu. A single test with the same title or guide screen gives you a direct comparison with normal standby.
Judge the result over a second start
If the app recovers, try the same test after another restart so you can tell whether recovery persists. If it fails again while other TV apps work, collect the app and TV software versions and ask the publisher about the exact symptom. Return Quick Start+ to your preferred setting after testing. Allow the television to finish any visible software update before using any shutdown procedure.
