Resolution problem that occurs when I see the built screen on mobile after I build it with Webgl.

[jhj198988]

Currently, I am using the Unity version 2021.3.11f1 and I am testing it by build it with Webgl.
When I build with Webgl, it comes out very well when I used a pc to look at the screen, but when I use a mobile to look at the screen, there is a resolution problem.
(The picture below shows a resolution problem when I look at the screen using a mobile. The resolution is much smaller than the screen on the mobile)

I am currently using Unity-webview-2020 for Webgl template, and I am using Default Canvas Width, Height 1920 and 1080.
Is there a solution?

Thank you for the report. #846 seemed to introduce this issue, which is now fixed by #860. Could you please try the latest?

I applied the latest version, but it's still the same.
The screen I saw on the mobile after build the webgl is shown in the picture below.

Hmm, at least the sample app seems to run without such an issue. I've put adjusted sample that can be directly built for webgl with 2021.3.11f1:

https://github.com/gree/unity-webview/tree/example-for-859/sample

and sample-webgl.zip is the build. The following is a screenshot of it running on iPhone Safari:

Problem solved.
It was solved by exporting the downloaded sample project(https://github.com/gree/unity-webview/tree/example-for-859/sample) itself and importing it into my project.
Thank you so much for your help!
