My channel is using GetDeviceUniqueID API to post data to my server just for statistic purpose. The document says that the API is going to be deprecated in Spring 2019. I try the new API GetChannelClientId() but it returns completely unrelated value. Does anyone know how I can switch to the new API without damaging my current statistic data?
By the way, what will happen after the API is really deprecated? Will the channel crash or the API just return blank value?
