The SQL syncing works great with the roles you want to sync with the ranks from permissions, however I noticed that the linked role from MinecraftDiscordAccountLinkedRoleNameToAddUserTo does not work as intended with the new SQL feature.

Example:
Bot1 on ServerA
Bot2 on ServerB

User types /discord link on ServerA and messages Bot2, all roles are syncs properly from GroupRoleSynchronizationRoleIdsToSync however they do not get the role applied from MinecraftDiscordAccountLinkedRoleNameToAddUserTo.

Current workaround is to have the user message the appropriate bot that's within the server. If I /discord link on ServerA, I must send this code to Bot1.

or you could add the "Linked" role as a part of GroupRoleSynchronizationRoleIdsToSync (just give everyone the permission), sql linking is currently experimental and will be fully polished in DiscordSRV2
