You seem to have a number of unresolved issues which you want to vent as publicly as possible and that is understandable.
The title of this topic is “Who will take the step toward the next Connected Steam Oven” This is about a future direction, so not sure it is the appropriate place to find solutions to any of your past and ongoing complaints. Community boards become dysfunctional and largely abandoned when every topic is steered into broad ranging negativity.
Perhaps initiate respectful discussion on your specific gripes, That would provide better focus for contributors as well as for Anova product managers and designers. Nothing can undo users’ past bad experiences, constructive criticism would be an easier read for all concerned.
