Has anyone tried to navigate the new Lifemiles award app?

Trying to book a Paris-Brisbane business class flight next year and checking Lifemiles awards regularly as it gets closer to my booking date.
When I try to search CDG-BNE on Thai, the message says “the origin/destination is not available for the selected airline…”; when I repeat the search using “Smart search”, Thai airways comes up in first listing?? Anyone know whey it will not list under Thai Airways.
Previously I was able to check Thai airlines directly. Anyone have any ideas why the change?
Also they now list economy, Business and First if available but economy and business columns have a heading “Limited seats” and “All seats”. Anyone have any idea why they are showing this?
Will appreciate any help or comments

I heard from some friends that they have updated their website interface recently. Their IT department has always been not the greatest. However, I don’t know what the new changes mean. Do they allow you to proceed with the redemption?

Thanks for the info, was thinking the same about their IT department.

Hopefully I will be able to make a redemption, but won’t know for about 10 days - will let you know.
