Nextcloud indication of synchronization of folders and files is not showing

NethServer Version: NethServer release 7.7.1908
Module: Nextcloud

Hello everyone !
I have a problem in which the indication of synchronization of folders and files is not showing, I uninstalled and did not solve it, at first it was showing.
I use Windows 10 Pro

NextCloud Client or WebBrowser?
If it’s the first one, consider to look for Nextcloud support…

Thank you very much for the answer, I already published the problem in the Nextcloud community, I understand that the problem is in the Nextcloud desktop client.
