Cannot upload files at some times

Question

Hi,

At some times, I can't upload files. This is the error I get:

And I figured out what's causing the issue:

-I've tried using a private tab (which disables all cookies and extensions that might be interfering)

-Also clearing cookies and logging back in (even in guest mode this keeps happening)

-Using a different browser

-Using a different network

I'm using the web version of copilot.

Thanks in advance
