I noticed many of my more advanced ones no longer work. The nice part is now that I have added speak around the code it no longer rambles off gibberish but it just doesn’t play anything.
It does play fine on this testing site I found. https://topvoiceapps.com/ssml

Those with sound clips don’t work either.

If anyone has figured it out please let me know.
