Installed latest beta on two macOS computers. Established sync chain between two computers, an iMac and MacBook Pro. iMac was the host, MacBook Pro the second computer. No syncing of information occured. The iMac did not show the MacBook Pro, the MacBook Pro did not show the iMac under the Sync section. Had sync set up to sync everything.
Downloaded the betas to try Sync v2 but not working at least in my case.
