I had the same problem with my R 23 within the first month of delivery last year. This was the reply from Andrew. Another owner in my area used Gorilla glue and it came unglued not long after his fix. Good luck.

Hey there John,
We certainly recognize that there is an issue with these glued on pieces sticking to the glass and are changing procedure in house. What I have done for ones that have come loose was use a black 5200 fast cure and sand the plastic block the catch is hooked to so I get a good bond. Clean the glass where it sticks really well. Tape it in place and let cure 24 hours. Seems to hold really well for the ones I have done locally. We are happy to cover it under warranty through Peter if you want to get in touch with him to have it fixed.
Thanks John,
