Hello,
I think, I’ve answered some of your questions and we don’t provide support via email which can’t be tracked.
Ticker options can be controlled via SilverMag pro theme options. You can display category or recent posts via Ticker. Since theme is responsive, layout will automatically changed to 2 coulmns for small screen, google uses small screen like 1024 for rendering.
Theme is not responsible for any rendering issues. If you have issues in google search console, Hire any SEO expert to solve this or send us your Google search console credentials. Normally We don’t provide support for Google issues, We only provide support for theme related issues.
Thanks
