bug: Ionic 4 IOS scroll issue

On IOS(12.4.1) sometimes scrollbar disappears(not rendered) and this happened on all pages.
How can we fix that ??

The issue is that the pointer-events: none; is changing its property but the scrolling remains frozen.
it unfreezes if you update any css property.

You can add the below css to your global.css file

.content-ios {
    pointer-events: auto !important;    // to fix scroll lock on ios

Hope this do the needful.
