Have to Delete the App each time I use mr RS250

Not sure if its the remote, or the streamer , but in order to stream, I have to delete my HiFi Rose application and download again, before the remote (apple iPad Pro) can be used as the remote. The HiFi rose icon shows up, but nothing loads. Sometime the generic icon without album cover will show with the title of the song, but the song never starts. Any suggestions?
