Sorry for confusing description.
I have a React app hosted on Netlify. I have uploaded bunch of images to be used within app, in png and webp formats. Most newly added images are fine, but somehow group of them when returned have this similar to the following response header:
content-type: text/html; charset=UTF-8
date: Thu, 21 Oct 2021 11:15:44 GMT
but same file in incognito mode has following response header:
date: Wed, 27 Oct 2021 21:04:28 GMT
Hard reloading page doesn’t help. So it feels like those images somehow cached, but I wonder why response header is different in icognito mode or in some other browser.
And I suspect that if they fail for me they might fail at least to some other users.
