Total used over 600 mins. App only shows 30 ish mins of captured c9nversation

I'm using the DIY friend device. I turn it on. It records and transcribes.fine but I'm showing a lot of usage and nothing much in my feed. Certainly not 600 mins. Also I find that I can't just record then choose the time period to transcribe a bummer.

I have this feature in soundcore. I like being able to flick a switch and know it's recording. I don't like it wasting minutes transcribing silence and I'm still baffled about 10 hours of usage but only 30 mins of use.
