 ### Fixes
 
+- UI/Usage: reload usage data immediately when timezone changes so Local/UTC toggles apply the selected date range without requiring a manual refresh. (#17774)
 - iOS/Screen: move `WKWebView` lifecycle ownership into `ScreenWebView` coordinator and explicit attach/detach flow to reduce gesture/lifecycle crash risk (`__NSArrayM insertObject:atIndex:` paths) during screen tab updates. (#20366) Thanks @ngutman.
 - Gateway/TUI: honor `agents.defaults.blockStreamingDefault` for `chat.send` by removing the hardcoded block-streaming disable override, so replies can use configured block-mode delivery. (#19693) Thanks @neipor.
 - Protocol/Apple: regenerate Swift gateway models for `push.test` so `pnpm protocol:check` stays green on main. Thanks @mbelinky.
