GOJS license apply

I am using gojs in my two products - one is based on React TypeScript and other is just including gojs file.
The one where i used React Typescript, gojs is installed using npm and version of 1.8 is used and setting license key works properly (watermark is removed).

The other product where i use gojs by adding the script file , I used version 1.6 and i got the specific file downloaded. Now i wanted to upgrade same with 1.8 or higher as some function is not available in 1.6 version. But now trying to apply license there doesn’t remove the watermark.

What I need to do for same ?

I have already replied to your email message.

Yes. it worked … needs to adapt the code. i overlooked same.
