Greetings!
Thank you for posting in Microsoft Community.
We very much appreciate you for sharing some of your feedback and suggestion. At this time, Microsoft has not announced any plans to integrate Loop with Github. However, I will pass along your suggestion to our product team for consideration as we very much value every users feedback and ideas.
In the meantime, you can still use Loop to collaborate with your team and share updates on your Github projects by manually sharing links to your Github project boards within Loop.
Also, it would be more appealing if you can also send a feedback directly to the Microsoft Loop developer team. In order for them to get notified about this very useful idea that you have and apply it in the next upcoming updates. We would like you to also remember that Microsoft Loop is still in preview so it is best if you share your feedback as soon as possible.
Here's how:
During this preview we want to hear from you to help improve your experience – so send us your feedback in the app to help us shape the journey.
In the bottom right corner, select Help> Give feedback.

On Android or iOS, tap your profile picture at the top left to find Help and feedback.
