Identify the stored item
A guide, a playlist, artwork and a media segment are different resources with different update patterns. A 304 for a logo says nothing about a programme schedule. Record which item appears stale and which request the response actually belongs to.
A player can combine freshly downloaded data with older local information. That is why a newly loaded screen can still show an out-of-date title. Before clearing anything, note the visible schedule date, programme label and the player's last refresh indicator if it provides one.
Compare content, not just status codes
Use the application's ordinary refresh once and check a specific expected change. For example, compare the guide entry for a known programme time with the current official broadcaster schedule. Check time-zone settings separately so that a clock offset is not mistaken for stale data.
If a refresh does not change the entry, preserve the result. A 304 may be perfectly correct for the resource the server validated while another data source needs updating. Support needs the affected item and date, rather than a general request to disable all caching.
Why indiscriminate clearing can hide evidence
Imagine an illustrative guide that still shows yesterday's schedule while a cached image validates successfully with 304. Clearing every application field may remove the old guide, account entry and favourites together, making the original fault harder to reproduce. Clearing the image would not address the schedule source anyway.
A narrower supported guide refresh or guide-only reset, where the player actually offers one, preserves more useful context. Obtain platform-specific steps from the correct player documentation; cache controls are not identical across applications and televisions.
Escalate the mismatch precisely
Provide the programme, channel label, expected schedule source, displayed time zone and refresh time. If diagnostics identify the resource receiving 304, report its role without exposing its full private address. Ask whether the guide publication or cache-validation data needs correction.
Do not assume that a successful cache validation proves the server's programme information is accurate. Validation answers whether a representation changed according to the server's validators; editorial correctness and regional schedule accuracy are separate questions.

Should a 304 response contain the whole programme guide?
No. The purpose of the response is to let the client reuse a stored representation rather than download it again.
