Input Field Not Showing in Landscape Mode on iPhone Safari

[kumamaru3]

When I display a WebGL app (https://kou-yeung.github.io/webgl_input_sample/default/index.html) in landscape mode on my iPhone's Safari and tap on the input field, the input field at the bottom of the screen does not appear.

Thanks for reporting this!

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.
