Lost connection to host every 15 minutes

[Stephen Cairncross]

Hi, I’ve recently just bought Grounded 1 on my PS5 to play with my girlfriend who plays on a Xbox One. I was really excited to play and we enjoyed the 15 minutes of gameplay we had, until it kept kicking the joined player every 15 minutes, saying something like “lost connection to host”. I’ve done some research and apparently this has been an ongoing issue for years. I really really want to play this game with her but we can’t progress anywhere when it keeps doing this. Is there any solution to this problem?
