If you just purchased Amazon Cloud Drive and Plex Cloud then you can still cancel it (as long as it hasn’t been 90 days past the free trial period). No word on any refunds for the matter since Amazon’s Cloud still works well on their end. Plex states that the Plex Cloud service still works well with other cloud services like Google Drive, Microsoft’s OneDrive and Dropbox. Now might be the time to switch over to another cloud provider if you can.
