I understand you’re less than pleased with the timeliness of our support team, but this is absolutely false. Every email sent to us is triaged against known issues, and if something hasn’t been reported yet our Support team members can create a development ticket directly from their Support portal.
The best place for all bug reports is support@smartthings.com.
