@Pothulapati 👋 I hope you are well! 💡 Tip: when creating issues, I recommend adding the team's related project. Why? This is a signal that the issue is being added to their inbox, and requires investigation. In the case of Team Workspace, we also have a Zapier Zap that notifies us via Slack when such issues are added to our inbox (which is super convenient for me as an EM).
