Not sure if you are aware of the relationship between Somnio Global and PO3. Also not sure if you are aware of the relationship between Hyundai and Somnio Global.

However - I do agree with you that it would have been announced if the air purifier in the 2021 model was an FRG unit.
Then again - I also sometimes wonder if the board remembers that PO3 is a publicly listed company.
If anything - this all just tends to suggest to me just how close PO3 could have / should have been to translating the tech into a commercially attractive proposition that aligns with what the world needs right now.
Whether PO3 has 'missed the boat' remains to be seen. It's going to take a mighty significant update on activities to restore investor confidence. If there has been material progress but the market hasn't been told - the SP could move rapidly from where it sits now. But if the update is all about what is going to happen (rather than what has happened) - I'd have pretty major concerns about where the bottom may be.
GLTAH - hope you all make truckloads of cash this week.
