Audio transcript not working in Zoho notebook

Audio transcript not working in Zoho notebook

Greetings all!
I'm enjoying the Zoho notebook as I tested out over other notebook applications. I would really love the audio transcripts to work as that would save us a lot of time so that we can utilize the notes from an audio recording. Currently when I try to utilize this feature both on the web via browser the Windows desktop app or the Android app, it does not appear to be working. Is this a known issue? I'm unable to get the transcript from the audio on any of these platforms. Is anybody else having this issue? Is there a work around or is this something that is currently being fixed? 
Thank you for all the hard work that has been going into the Zoho notebook. PS on a side note I also would love to see sub notebooks within notebooks. A tree structure I think some are calling it.
