same i waited and waited, then came to the same conclusion, its always in the down position so I went with the one for the down. this is the one i got https://www.amazon.ca/SMARTLINER-Weather-Custom-Position-Seltos/dp/B088C2XL6C/ref=sr_1_1?dchild=1&keywords=SMARTLINER+seltos&qid=1624627531&s=automotive&sr=1-1
came rolled up but after leaving it out for a day under some books in each corner it flattened out perfectly.
now it will still fit in the up position with a little help, but due to the angle of the back seats its not perfect and even though the trunk closes and locks, it doesn't LOCK as in my key fob wont do the little beep when i hit lock as the trunk lid is out about a mil , which is really annoying.
Looks like it’s still available on Amazon.
You could consider seat belt plugs. They are just a few bucks on amazon and if you often drive solo and wish you could just leave your bag on the front seat or be able to set you ipad down on the passenger seat... this is a good solution.
