CMP stub not working with Google Ad Manger CMP (Funding Choices)

[taddis]

Version
1.4.0

Module (core, cmpapi, cli, stub, or testing)
stub

Describe with reproduction steps – What is the expected behavior?

• Make sure you have Google Ad Manager privacy and messaging setup and working for a webpage.
• Build the stub as shown in the README
• Add it directly to the page before gpt.js script.
• Expected behaviour is that the Google Ad Manager privacy and messaging popup should show.
• Current behaviour is that nothing is shown.

Simmilar issue here, we imported via npm

import * as cmpstub from '@iabtcf/stub';

cmpstub();

Google Funding Choices is also loaded from gpt.js

For us the panel will show when using ?fc=alwaysshow but not when accessing the site with fresh cache/cookies in incognito

Hi, any news on this? It seems that it is still happening.

@danielfx90 @taddis Is this still reproducible with that latest library found here: "@iabtechlabtcf/stub"?
