Roon Radio iPad versus IPhone

I’m new to Roon and have just subscribed for a year. I’m on 1.8 and have a question regarding what appears to be a difference between iPad and iPhone implementations with regard to Roon Radio. On iPad I have the option of giving a thumbs up or down on the now playing track and also on the next up (to determine if it is added to the queue or not). On the iPhone I only see the ability to thumbs up or thumbs down on the next up. As others have pointed out elsewhere it is likely I have no idea whether I will like the next up or not, so as far as the iphone client is concerned it is pretty useless to me for Roon Radio as I cannot thumbs up or down once I am listening to the track. Am I missing something?
