"Player must allow resource packs to participate in resource packs." It doesn't work.

My friend who plays with me said he couldn't see the bed, so I checked and found out that there was no check mark on "Player must allow resospack to participate in resospack", so I checked it again after checking it and it didn't apply and tried many times. How do I solve it?

I've checked on Android, and they can't do everything.
