Just updating DCPU's post re. the fixing arrangements in the M1 version.
I tried to remove mine recently and frankly it was very difficult. There is a large washer and a smaller washer separated sufficiently to slot in a keyhole. see illustration #1. You pull the bolts against the spring pressure just enough to relieve pressure on the washers and then try and remove the barrier. There is very little tolerance to remove the barrier without it catching either side.. then the spring loaded fixing can get wedged deep in the "keyhole" requiring the keyhole to be dismantled to remove the internal stiffener.
After finally removing the barrier I channelled Jean Mercier
and "dismounted/dismantled" the spring loaded screw mechanism and reassembled it with the spring on the other side of the bracket so that it now needs to be compressed/pushed to insert into the keyhole. (Illustration #2)

It is now straightforward: offer the barrier up to the keyhole, compress the bolts simultaneously outwards with your thumbs (rather than trying to compress the spring in the opposite direction! for which you need 4 hands!: two to hold the barrier and one each side to pull the bolts back against the spring pressure to clear the keyhole) and insert the bolts, release the pressure. The bolts are now locked in position.
To remove the barrier, simultaneously press the bolts sufficiently to free the barrier, align with the top of the keyhole on each side and release the pressure. They pop out automatically!!
(I shouldn't speculate.. but I reckon the spring locking mechanism has been wrongly assembled in production. If there's a valid engineering reason why this "re-jigged" arrangement is wrong, I'd gladly be corrected.)
