Hi, I just found that many tabs in my Safari Web Inspector are no longer there. For example, previously, I have the following tabs in Web Inspector: Inspector: Elements; Network; Sources; Timelines; Storage; Graphics; Layers; Audit; Console; But now, I only have: Console; Sources; Audit; Does anyone know the root cause, and how I can restore the missing tabs? Thanks much. My OS: macOS Catalina, 10.15.7 Xcode: 12.4 Safari: 14.1.1

Hi, I posted a question before that many tabs in my Safari 14.1.1 Web Inspector are no longer there on Catalina. Original question is here: https://developer.apple.com/forums/thread/680886 I upgraded my OS from Catalina 10.15.7 to Big Sur 11.3.1, then the issue is resolved, so I resolved the original posted question. However, after I upgraded OS to Big Sur 11.4, the issue comes again. I tried to install "Safari Technology Preview" https://developer.apple.com/safari/download/, but it will not resolve the missing tab issue with iOS device or simulator. For example, if I launch any app with webview in iOS simulator, then launch Safari, go to "Develop" -> "Simulator", then I can only see 3 tabs: Console, Sources, Audit, and none of them are working actually. Can someone help take a look, and let me know if anything I can do to unblock myself? Thanks.
