What is the Windows desktop client sync frequency?

I am testing the latest Nextcloud 11 between a Windows 10 and a Windows 7 machine, with a CentOS 6 server.

If I upload a add a small text file on one Windows machine, it will sync almost instantly to the server (as I would expect). The file shows up in the web GUI without an issue.

However it will not download on the other Windows machine without some prompting. If I open up the Activity tab on the other machine my file upload shows up in the activity tab, but the file won’t download onto that client unless I do something inside the Nextcloud folder, such as adding another file. At that point the problematic file will download.

Am I missing something in the setup?

Thanks!
