Hey, I have a bungeecord network. Luckperms Bungee on my bungee, rest are Luckperms spigot.

lp info

lpb info

All the permissions are synced, doing lbp editor and lp editor will show the same permission nodes.
I have advancedBan running on my bungee, all the perms added to my mods. For some reason my mod team cannot /tempban as it says no perms.
i tried running a command /lpb <user> permission set ab.ban.temp true and the tempban worked.

i'm pretty sure that the bungee commands should work since everything is in sync.. am i doing something wrong?

Make sure the UUIDs match, when you run lp(b) user <user> info.

If they don't be sure to follow this: https://github.com/lucko/LuckPerms/wiki/Network-Installation#pre-setup

That guide is how I installed LPB and LP. I'm pretty sure all UUIDs match cz it's happening to all of my mods.

Any updates on this?

Yes it would happen to all players. Please verify they match.
