input type='file' not working in instagram in-app browser

Question

When you try to upload a file using input type='file' on a webpage that is opened in the instagram in-app browser, the page just reloads. In facebook in-app browser there is no such problem.

Answer 1

Just in case this will still be useful to somebody, I had a similar problem, except in my case when I clicked on a "choose file" button nothing happened at all. I fixed it by changing the accept attribute of the button to contain only mime types and not extensions.

So this:

<input
  type="file"
  accept=".jpg,.png,.svg"
/>

Should be replaced by this:

<input
  type="file"
  accept="image/jpeg,image/png,image/svg+xml"
/>

This is very confusing because the first version works in all other browsers and docs at MDN also mention that it is correct.
