The hive texture pack isn’t downloading when I join the server, so I don’t see the custom items. I think it’s because I downgraded to 1.16.40, but I’m not sure.
Hive Bedrock only supports 1.16.100+
I don’t think this is correct. According to the support page, the server supports 1.16.40.
Try going into your storage settings on the main menu > cached data, and delete anything related to the Hive.
Yeah Hive supports 1.16.40, but the texture pack doesn’t download on that version. When I updated to 1.16.100, I got the pack. So I think Minecraft doesn’t download the pack on the version.
