My dude, I spent many thousands of dollars on Heroku over many years. I've reported bugs to customer support and nothing changed or improved, for years. I appreciate you're reaching out, but that bridge is burnt. The trust is gone. I ran into a bit of trouble getting set up with Render and one of their PMs reached out directly to learn more. Heroku replied to virtually all of my customer support issues with messages gaslighting me that the problems were my fault or "Try debugging your application with New Relic".

Forget little bugs... the big picture is far more important. I cannot recommend anyone use this product given recent (years) inattention.

Since you work for Heroku / Salesforce, letting your users know if this is a dead product or not would be a good first step. If not dead, explain why there have been no updates and what is to be expected moving forward.
