aanabanana review for Upload‑Lift Image Upload

I have used this app on and off and it seemed to be working fine but recently my customers have started to complain that it missed uploading the file a few times. I am losing business because of this. *so they replied stating it is a problem with my theme (my site has same theme for 2 years now) . You guys just do not want to accept the problem and keep passing the blame to something else. Disappointing!
