Main‑menu panorama cache bug on iOS after app restart

This bug exists in Minecraft Bedrock v26.51 running on iPhone 8 Plus, iOS 16.7.16.
If I delete the Minecraft app and redownload it, the very first launch shows the correct Pale Garden main‑menu panorama.
But after I fully close the Minecraft app from background and open the game a second time, it always loads the Ancient City deep‑dark panorama instead.
Everything inside game worlds works fine. Only the main‑menu background cache is broken.In some cases, it may also load older panorama from previous updates, such as the Nether Update background.This bug does not happen every time. It occurs probabilistically after fully killing the app from background and restart Minecraft. It does not occur when just switching back from background.
