B2B Sync button not working
I am on version 19.232.1124.0010 and been speaking to O365 support since 10/01/20 and still no further forward in fixing the issue. O365 support are trying but can't seem to identify the cause.
Ended up giving up as couldn't get it to work. These links might be of use to you:

All I can say is good luck in your B2B setup and if you find the golden nugget of how to make it work please share.
The issue seems to be MFA related.
Known issues with this release:
-On the Mac, Files On-Demand thumbnails will not display from external organization's sites. Thumbnails will display correctly for files from the user's own organization.
-On the Mac, if the guest account was created with a different email address format than the form they are using with the sync app, the external site's content cannot be synced. For
example, first.last@fabrikam.com vs alias@fabrikam.com.
-On the Mac, the external content may be placed on the local computer in the user's own organization's folder instead of one with the external organization's name.
-Multi-Factor Authentication from an external organization is not yet supported. Only guest accounts that don't require MFA will sync.
