Applies to Sinch Contact Pro version FP19
You are not able to get Sinch Chat working even though the configuration is done according to documentation.
Change the address from @sinchchat.sinchconversation.com to @nativechannel.sinchconversation.com in your queue configuration.
I think the documentations should also be changed. For FP19 On-Premise and Cloud the documentation suggests to use @shinchchat.sinchconversation.com. For me atleast it was the reason why I contacted support and was told to use @nativechannel... instead.
Also I don't think that Sinch Chat can be used with FP18. Atleast that's what support told me and the FP18 On Premise documentation doesn't have anything in it regarding Sinch Chat configuration via Conversation API.
I think hotfix would be more appropriate. There are many customers under SAP contract on the newest version FP18, as FP19 is not yet available for them.
Please, reconsider this, we have to put one starting project on hold because of this problem.
Thanks and regards,
