For anyone looking into turning cache off this at a later point
of time:
Open
developer tools, go to “Network” tab, and click the small Block icon with a
line through which says “Ignore the resource cache when loading resources” in
the top right corner next to the trash icon.
It worked out for me. For anyone is looking to turn off the cache. Hope it helps.
