Too Many Streams (Error 30004-005)

My roommate and I have Directv stream (Account is under his name). We initially had 1 device set up on our home network, and then I set up 3 devices at my parent's house since I was under the impression that there could be 3 simultaneous streams outside of the home location. It initially worked, but then my parents told me they were getting an error message that told them that there is a limit of 2 simultaneous streams, and that they need to either refresh the stream or set new home location. I even recently set up my own firestick at our home network to make for 2 in home devices, and it even gave me the same error message, which confused me because I was connected to the home network and didn't think I'd need to set new home location because it should've detected that I was on the home network. I was at least able to set new home location on my firestick and got that to work, but my parents aren't able to watch on ANY of their 3 devices I set up for them. It's not just an issue of them trying 3 at a time and one not connecting (Which, again, is confusing considering I read on the website that there is allowed to be 3 simultaneous streams), but they can't get ANY of the streams to work. This is incredibly frustrating and I've tried to chat with an agent only to not get any sort of response in a timely manner. Any help would be appreciated.
