You have to press it in very carefully. Start at a corner, press it into the groove in the door....and do that around the entire door, especially in the corners. Mine hasn't popped out in a llooooong time. No glue.
You could try a very small film of "Amazing Goop." You probably won't need it all the way around the gasket and you don't need a massive amount. Amazing goop can be found at Lowe's as well as many hardware stores.
Not sure where I saw it recommended, but I ended up using this 3M adhesive here. Did it this summer so I haven't used it a ton, but so far it's been working great.
I used "Shoe Goo". Smell goes away after it cures and tube will last for years if kept in refrigerator. Good for many different permeant glue repair jobs.
owner of a 2020 320-s ( does the s mean it is faster? ) I used Loctite 480 with a few dabs spaced apart 6 inches all the way around. So far, the gasket has not moved.
