Hi,
we are currently using a version of your Unity Client SDK released in April which contains the call 'GetUserCombinedInfo'. We recently noticed that this API call has been deprecated in status 'proposed', which is the first stage of deprecation as can be seen in this post entry. The recommendation is to use 'GetPlayerCombinedInfo' instead, but this method is not available in our SDK version, so we should upgrade it to version 2. The point is that we are pretty close to launch our game and this migration would suppose a problem. Despite we have read in your post that one of your core commitments is that the API methods used by a title will continue to work, it's also pointed that in some certain cases this could not be valid. So the purpose of this post was just to ensure that the mentioned API call will remain functional.
Thanks in advance for your help.
