Out of frustration one might end up installing chrome app/plugin to forcefully clear cache. One of them is "Clear Cache"
Interestingly chrome has now created a very discreet "Empty Cache and Hard Reload" option for developers. To see this option open developer tools by pressing F12 and then press and hold reload button. I have been using this option from past one week and it worked every time as expected.
|Chrome Hard Reload for Open UI|
Please be mindful that this is an hidden menu and only shows up when chrome's developer tools are open.
Happy coding :)
