Glass rendering and stability

Hi! Not sure if it's a bug?! My model has glass in it and in adobe dimension it looks great! But when i view it in aero : 

1- the shine /reflection is gone

2- the model seems unstable and keeps moving , can't reach the wall to read what's on it😂 

my file is 3.5MB 

Am using iphone pro m13

latest aero version 

would really appreciate any help tkx!
