Keep the first screen useful
If supported, save a small favourites list and check text size or orientation options. Only organise sources you are authorised to use; a renamed category does not change your plan allowance or access rights.
Refresh deliberately
Record the current configuration privately before changing it, then test one documented refresh. Avoid doing this while repeatedly switching networks. If the result is unexpected, note the device and player version, and keep playlist addresses out of public messages.
Make one small-screen change at a time
1. Keep the current playlist configuration privately. 2. Add a few authorised favourites using documented controls. 3. Check whether labels remain readable after rotating the screen. If navigation is better but playback still fails, treat that as a separate issue; do not replace the source to fix a display problem.
