Why can I not Pause and rewind live TV with Spectrum TV the same as AT&T Direct TV?

I just switched from AT&T U-verse to Spectrum TV and found out that I lost some functionality that was never noted to me by Spectrum; primarily the function to Pause & rewind live TV, when using Apple TV or Roku streaming devices. I had a choice of switching either to AT&T Direct TV Stream or to Spectrum TV and selected Spectrum as a superior product. Now I find out that there are basic viewing functionalities that Spectrum cannot offer that are offered by AT&T Direct TV. Why can't Spectrum provide this functionality, the same as their competitor?
