Hates being on his tummy


So my 6 month old hates being in his tummy, I did tummy time with him loads as a baby and he learnt to roll from his tummy to his back at only 3 months but now he hates it. He will not roll onto his tummy and shows no signs of crawling as as soon as he’s on his tummy he gets so angry and frustrated. I’m not bothered about the not crawling as I know some babies don’t crawl. Does anyone else little ones hate this?
