Lately I've been having this issue where the siri voice won't download to my apple watch series 4 so I can use it with VO. Every time I check, it says: "Waiting to download. Download will occur when your watch is charging." Only I've kept the watch on charge for a while and...nothing's happened. Funnily enough, Siri on the watch still uses the same voice, so I don't know what the issue is here. Is there a method to allow the download of VO's version of the siri voice to occur so that I can use it? Currently running the latest version of watch OS.
