I’m also facing the same issue and chatra chat app is not working my website so any suggestion what to do
Can you go to https://dash.cloudflare.com/redirect?zone=apps/installed-apps, and select the website in question, if prompted? It should show a list of the apps installed, can you post a screenshot of that here?
Also, have you configured it on their end, i.e. signed up through Chatra etc.?
