• Map checks now use a location appropriate for each map: Beijing for China maps and China-only custom maps, and New York for other maps. Checks also respect the map's maximum zoom level, reducing false failures caused by unsupported locations or zoom levels.
• Added a check toggle for custom maps. Turning it off skips startup checks and related network diagnostic tests while keeping the manual Test button available. The setting is preserved when importing and exporting custom maps.
• Hybrid maps now skip image checks, while the fallback map is checked independently. Startup checks, network diagnostics, and custom map test previews now use consistent test locations, and failure messages show the city being tested.
• Switching maps or toggling the fallback map now shows progress while clearing the cache and applying map settings. The indicator appears beside the primary map title without making the controls jump or flashing during quick switches.

• 地图检查现在会根据图源选择合适的位置：中国地图及仅限中国区域的自定义地图检查北京，其他地图检查纽约；同时遵守图源支持的最高缩放层级，减少检测位置或层级不受支持导致的误报。
• 新增自定义地图检测开关。关闭后会跳过启动检查及相关网络诊断测试，仍可使用“测试”按钮手动检查；导入、导出自定义地图时会保留此设置。
• 混合地图现在会跳过图像检查，备用地图仍会独立检查。启动检查、网络诊断与自定义地图测试预览统一使用相同的检测位置，失败提示会显示实际检测的城市。
• 切换地图或开关备用地图时，现在会显示缓存清理与地图设置应用进度。提示位于主地图标题旁，避免控件上下跳动及快速切换时提示闪烁。
