I think my post was promoting my webapp prototype “too much”, so it got removed. Which is also surprising when you think about the number of posts on the forum from other folks that promotes their owne business. This violates rule #5 from the community rules.
I managed to get some feedback from folks recently. It’s been great so far! 
I am now using the prototype to track my investment with Freetrade, I have ditched my old spreadsheet. Still not perfect, but it’s getting there.
