Hi, I am having a problem with the parallax effect on the mobile version for iOS, to be precise iPhone 12. It works normally on android but not on iPhone. Also, this is only happening on this website. there are others that I have created that work normally. Any idea why this is happening though?

It’s working fine on my iPhone 12 mini, too. Safari & Firefox
Thanks a lot guys, Im doing some corrections I think I had a bug.
Does the parallax works for you or is a static image?
parallax is working
also on my iPad
Yes, just fixed everything manually now. Thank you so much for confirming it works 
You are very welcome.
Bonne journée
Merci beaucoup, toi aussi 
I am having the same issue. I have a parallax background on mobile view and it looks fine in preview mode on blocs while you scroll, does the same when exported and tested in safari with responsive mode.
Now when I test on a real device (iPhone 11pro with iOs 15 and safari) it doesn´t show the image and neither the effect. Any idea why could be this?
I have set the background as fixed and center top alignment to ensure the display
