As a Unito user, this is relevant for our company. The Product department uses Notion as a roadmap, as it makes it easy to align with stakeholders and collaborate with them on the issues. The Tech department are using GitHub, with Issues as a way to track large bodies of work and Task lists to break it down into smaller pieces.

Without the ability to sync the tasks, it is a challenge to have an overview on development progress on the roadmap, as it requires back-and-forth between the two tools, Notion and GitHub :)
