Smooth Sync: Sync your Transforms Smoothly across the network

Hello. I just purchased it.
What I hoped for this plugin is “launch character” is also synced well.
But launch character is still not synced.

I wanna launch my character during some periods by tick function.
When I launch character on server, the position is not synced at all.
When I launch character on multicast/client, the character is stuttering up and down.

The problem is not occurred in editor, but only in the package build.
(both are dedicated server - client)

is there I can do with this plugin?
