I can't seem to join my friends realm on Xbox One. The realm is called "Lockdown Town" and when I try connecting, I get stuck on a loading screen with "loading resource packs". It occasionally lets me join, after 20 minutes of waiting. Other times, it will just say I'm "unable to connect to world" and stop trying to connect. I never used to have this issue, and it's infuriating since all my friends are playing and I can't. I have checked online for any fixes and there are no definitive answers other than general troubleshooting like re-installing, hard restarting, etc. None of these 'fixes' seem to work either. Please help, thank you.
