Nextcloud windows client agent not syncing external storage changes continuously

Hi,
We are using Nextcloud 16 with shared external storage (SMB file server) and we have one issue with windows desktop client agent. If we are doing any changes in offline folder it’s syncing quickly to our file server. But if we are doing any changes in file server itself, it’s not syncing to client computer until we practice some changes in offline folder.

My requirement is if any changes doing in file server, it’s need to sync to all client computers configured client agent.
Your support is highly appreciated to solve this issue.
