I paid for and downloaded the Medica template. I only slightly modified the template by doing the following:
- Changed images
- Commented out sections I didn't need
- Changed text
- Added an extra slide to the slideshow on the home page
I made no structural / JS / CSS changes at all. Yet, when I test on iOS (iPhone 5c) Safari, the scrolling jumps and sticks when attempting to scroll over images.
As a further test, I opened the preview of the template on my iPhone using this link: https://colorlib.com/preview/theme/medica/
The problem persisted using the template preview. Can anyone else reproduce this?
