iTunes on iPad won’t even show rentals

I am logged into an iPhone and iPad simultaneously with my Apple ID. I rented two movies from iTunes on my phone. Although they show up on my phone they are to be seen nowhere on the iPad. I have tried restarting the iPad and have logged out from and in to my Apple account. Nothing worked. However you can see a movie I bought several days ago can be seen on both devices. I am not sure what this means. Is it because I rented them less than an hour ago? I did not want to go down the try renting again and see if it says “You have already rented this.” method because I have ended up renting a movie twice before because of an error. (I am not entirely sure about the generation of the iPad however my iPhone is an 8.)
