Adjusting the stub code
The stub code (the part of the code that you intergate into your website) automatically includes support for IAB TCF v1, IAB TCF v2 and IAB USP. In some cases, the support for both IAB TCF versions can cause issues. In order to avoid these, you can reformat your stub code as follows:
