Shower screen right angle drop

[Surftuzzer]

Hi - just moved into a house and the shower screen is proving a bit crap... the reason for the post is because this metal right angle that holds the smaller glass to the main glass panel isn't held well. if you look to the bottom, at the (brighter blue) smaller glass, the issue is that it sinks down. Eventually it is too low (and gets stuck on the side of the bath) so I have to jiggle it up 5-10mm to where it should be. 2-3 showers later its down again. The seals need a tweak in the corner, as you can see, but I'm not worried about that. I would love to hear from anyone who has a solution to this. The main glass panel is fine. Angle is fine. its just the metal holder for the smaller glass part that is not doing its job. Surely I won't have to replace the whole screen?

Lift it up into some glue to prevent it dropping.

thanks foxhole, I guess that all I can do. Able to suggest a glue?

2 part resin did the job.
Wriggled the smaller glass down just an inch or so. Added so resin top and bottom. Wriggled it back up. Support the weight while it cures. Wiped off excess. Been solid for months now
