Remote Configuration

Hi All,

I am in the process of creating a Xamarin app and was wondering if there was a standard way of being able to configure the app remotely without having to republish. I haven't looked to much at firebase since we are in Azure but it looks as though they have something called Remote Config (which looks promising) and I cannot see if there is a comparable Azure service. As an example in our case we use Okta for authentication in sample code we have found the Okta clientid etc embedded into the code. What has happened while testing is that someone has deleted the Okta application and so it has to be reregistered which generates a new clientid. In the meantime our application would need to go through a republish (if we followed the samples and embedded the information). So in short I was wondering if there was a way through Azure to be able to support remote config changes.
One way I have been told of is to have a public service that could provide the details but it seems I would have to call that periodically for changes rather than have default values and then push updates as in the Firebase model.

Thanks in Advance
