I’m not disputing that you experienced extremely unacceptable performance delays while testing ActionTiles; but I’m saying that such delays are absolutely not characteristic of our product.
I don’t know why such a problem occurred for you, but as a certified "Works With SmartThings"™ product, we are committed to providing customer support to investigate and resolve such problems, including partnering with SmartThing back-end engineers when required.
So all I am asking of you is to considering spending a bit of diagnostic effort with
Support@ActionTiles.com and we will resolve the anomaly that you ran into. Indeed, if you have happen to have run into an as yet undiscovered bug or a compatibility scenario, then I am also concerned that other customers may be experiencing it and just not telling us. (Nobody has reported this though, including our thorough Beta participants.).
By helping us help you, you will be making a valuable contribution to the SmartThings Community (yes; the exact same community that is offering assistance and various helpful options and explanations to your inquiry and to hundreds of other folks in this Community Forum).
ActionTiles doesn’t resolve all the limitations of the SmartThings mobile app. We are a supplemental companion app that is designed to fill certain gaps very well, such as, “Guest Access”, the title of this Topic.
