Can't access some comments

Sometimes (not always), I can't access comments of my own solution, from notification (url example) or from another usual way. I can see my solution but not comments (and eventually not votes). So I can't answer them. It is getting a bit annoying.

I tried multiple browsers (firefox, google chrome, edge, brave), it is the same. And yet I found a way to access comments, a basic script.

import requests
url = ...
print(requests.get(url).text)

So the content is accessible (view source code from browsers also works) but is not displayed, which is even more frustrating.
