This is amazing to see. Thanks for the diligence that you put into this! I’ve asked the team to connect with you to see if we can help you to get your new place set up so that you can keep going with the great feedback and perspective.
The good news is that the engine behind scheduled and triggered SmartApps (which includes Routines as well which are just another type of SmartApp from the perspective of the platform) will be totally replaced over the coming weeks. Our support team will have the ability to turn it on in beta for specific accounts, so those on this thread who are interested could help us to get it fully tested more quickly.
Those improvements should dramatically impact the top issues that you found in your tracking.
