So here's how the different communication channels work.
If you have a question or need help troubleshooting a problem, then use the forum. But please do a search first, since there's likely others that have created a topic about it.
If you are seeing a bug in Metabase, which can be reproduced, then first search GitHub for existing issues and if you find an existing issue, then click on the first post to upvote the issue. Do not leave a comment unless it adds context to that specific issue.
If you do not find an existing issue, then create a new issue and provide all the information requested - specifically the steps to reproduce, so anyone can reproduce the problem.
