WebDAV and Google Drive

Additional Dropbox storage is simply too expensive compared with Google Drive’s storage prices. allows me to access my Gdrive through WebDAV, however, the setup procedure for syncing DT through WebDAV is less than intuitive. I have filled out the dialog box information that DT asks for when syncing through WebDAV, and a syncstore is created on my Google Drive by Devonthink, however, no files actually get synced. The store remains at 0 KB and nothing I do changes that, this is the case for any other WebDAV compatible server I try to use. The store gets created and then nothing. DT seems to be able to access and sync but it just doesn’t do anything beyond creating the store on the servers I’m trying to use. Any advice for how to fix this, or is this a problem with WebDAV sync?
