Custom Liquid Not Showing Up On Mobile but shows in the preview

Topic summary

The Issue:

  • Both widgets work in preview mode but not on actual mobile devices
  • The code includes JavaScript that loads external scripts from cz.im9.cz and sk.im9.cz

Identified Problem:
A community member analyzed the code and identified the gjs.php file as the source of the mobile compatibility issue.

Current Status:
The discussion remains unresolved. A third user with the identical problem asked for clarification about the solution—specifically whether to delete the problematic file reference—but received no response. No concrete fix or workaround has been provided yet.
