DAWTER is one person. You will get a reply from them, not a queue.
Before you write: the troubleshooting page covers the common ones — a bounce that was not found, an unplugged drive, a cloud folder that has not finished syncing, and the macOS warning on first open.
It is recorded and I have been emailed. You will get a reply at the address you gave.
If DAWTER is open, the user menu → Report a bug is better than this page for anything broken: it attaches your version, your platform and the recent errors, so the problem arrives already half diagnosed. Use this page when the app will not open, or when it is not a bug.
