AC Question

I have 2 game apps on my tablet that will NOT auto rotate to horizontal view...open in a vertical view only. I have checked and re-set auto rotate several times. It is the 2, I have others that rotate fine.
Device model is SM-T530.
Games: Flower Mania from Amazon Underground and Word Cookies from Google Play store
Any suggestions?
