Google assistant stops playing radio when I ask it to rewind

Hi there,
I use my Google Home to listen to radio on Tunein or IHeartRadio. Often I will ask it to rewind the feed x amount of minutes, and usually it does so with no problem. However, sometimes when I will ask it to rewind, it stops to listen to me, then does nothing and goes silent. The radio app is no longer playing; I’ll even ask what is playing, and it’ll respond with “nothing is playing right now”. So then I have to ask it to play the radio app again. Any solutions to this issue? Is there a way to get back to the timestamp of where it was initially playing when I asked it to rewind so I don’t miss out on hearing any content?
