Does not sync with google drive – unzip zip tool(rar/un7z) pro Review

Purchased this version in order to sync extracted folders and files to google drive, but it will not connect. Dropbox gives a warning that the developers certificate is set to expire soon, so who knows how a much longer it will sync. Is this app even still supported?
