I've tested my app with same two devices. One of device with ios 11.2.5 and another one have 10.3.3. When i scroll down my page smooth scroll working fine on ios 11 but on 10 its not working as well. Any advice ? or something changed in 10.3.3 ? Here is my some code snippet html, body { -webkit-overflow-scrolling: touch; }
