Can anyone help me to resolve an issue with implementing a post-chat survey after ending a chat? 

After I end the chat session, I could see a 'Leave a feedback' button and it takes me to the new page but the created survey is not showing but giving an error.

Created all in the sandbox following the steps from https://chatbotslife.com/salesforce-surveys-in-embedded-service-for-chat-formerly-snap-ins-76224fb6729f#ee02

Followed by https://chatbotslife.com/salesforce-surveys-in-embedded-service-for-chat-formerly-snap-ins-76224fb6729f#ee02

1. Created a feedback (grabbed surveyId as of 0Kd***************)
2. Created a community (grabbed networkId as of 0DB***************)
3. Added required object relationships
4. Added Chat Survey Redirect controller & page through Developer Console, Apex Classes > Profiles, and Visualforce Pages
(In Community Workspaces, Administration> Pages > there was no selection as of 'Community Builder Page', so I just selected 'Default Page')
5. Added Post-Chat URL to Chat BUtton configuration as of
'https://livechat-fg.cs35.force.com/fashiongo/SurveyRedirectPage'
(Can I use Post-Chat Page as of 'SurveyRedirectPage' instead of URL? It doesn't matter to use either Page or URL for Post-Chat?)
6. Created Process Builders, saved, and activated.
 
Also checked the CSP and CORS however this error appears.

Hello

I've been working on embedded live chat service in production and sandbox environment.

I found the custom chat header component is available to select in the Embedded Service Deployment Settings page. However I don't see any documentation about chat header component.

Also I don't see chat header option in the production environment. why do I have this option in the sandbox environment only? is there option that make it show or hide on the embedded service deployment page? 

please provide me detail informations how to enable chat header option in the production and how to implement custom chat header.

Thank you

Live chat of "Embedded Service Code Snippets" works well on desktop/mobile web but doesn't work on mobile app of iOS nor Android.

Steps to Reproduce
1. Copy "Embedded Service Code Snippets" of Live chat
2. Paste into index.html
3. Open index.html on ionic cordova app
4. Live chat icon is shown correctly, but it keeps spinning forever when clicking
