Mobile bottom input does not always show up on iOS (safari and chrome)

[StefanStrategis]

Hi,

The mobile bottom input only shows up on iphone when clicking one input while another is already selected, otherwise it doesnt show up. Causing the screen to scroll up only randomly (to show the bottom input).

I have not found a definite cause or a way to fix it, but I believe it's related to iOS restricting input related actions to actual touch events. And unity's input events not always being in sync with browser events.

I might be wrong. I will update if I find a cause or a solution.

We are using InputField, not TMP.

Thank you for your great work @kou-yeung

For mobile devices, the latest Unity versions already provide their own mobile input handling:
・InputField from Unity 2022.1
・TMP_InputField from Unity 2023.2

Could you please test the same project without using this plugin (WebGLInput) and check if the issue still occurs?

This will help us confirm whether the problem is caused by the plugin or by Unity’s built-in implementation on iOS Safari.
