First, we expect to begin ramping up invites starting December 5th! While we can’t promise when exactly you may receive an invitation, know that we are eager to share Plex Cloud with many more people as soon as possible. We can assure you that we will not rest until every one of you is up and Plexing in the Cloud!
Second, Starting today, we’re announcing new support for Google Drive, Dropbox, and Microsoft OneDrive! All three of these Cloud storage providers will be available to anyone whose account is chosen to participate in the beta. Now we’ve made managing your media in the Cloud more flexible by allowing you to link multiple Cloud storage providers, so you can create libraries with content from any of them.
Finally, while we have been able to introduce many new improvements to our underlying Plex Cloud infrastructure, we have run into technical challenges with the Amazon Drive integration. We are working hard to resolve the issues, so please stay tuned. In the meantime, we really hope you can help us test and validate the other Cloud storage provider integrations once we get you into the Beta.
