I have a Vegas Pro 365 subscription. And I've been using speech-to-text for months now. And randomly, yesterday, my ability to use this feature went away. Now when I try to select "speech-to-text" under "tools", I get the error message "This feature requires a VEGAS 365 license.". However, when I go to the Vegas Hub and select "My Profile", it shows my active subscription as "VEGAS Pro 365".
Also, as a side note, text-to-speech still works. Just not speech-to-text.
