How to increase my lab hours for the digital learning course

My lab hours got exhausted, I am trying to post message for help but no one is responding me. I also tried to reach customer support even.

Hello,

Can you please provide the name of the course?

Deploying a Model for Inference at Production Scale

Thanks.

I have granted you 4 more hours. In the future, you can avoid burning the usage limit by pressing the “Stop” button when you’ve finished with a module. If you need to save your progress, you can download the necessary files from the lab.

Thanks. Need 4 more hours. I completed this course. Not sure why it still shows 75%. Only the last exercise, the prometheus URL is giving 404. Please grant few additional hours.

You got it. I added four hours to your lab.
