The page(WKwebView) developed by SDK13 cannot be pinch-in on iPadOS13

Hello,


A few weeks ago, I released an application developed in SDK13 environment.

In iOS12,after the pinch-in operation, a reduced size screen is displayed.

However, in iPadOS13, it will return to the initial display size.


The following meta tags are set in HTML so that pinch-in and pinch-out can be performed.

<meta name="viewport" content="width=device-width, initial-scale=1.0,user-scalable=yes, shrink-to-fit=no">


I think something has changed from iPadOS13.

Can you help me? Thanks a lot!
