Serious OmniPod PDM failure and pump reconsiderations

I was indeed referring to the FDA and their concerns over a smartphone app to deliver insulin which is utterly ludicrous over that single failure system now. But it is 2020 now and we are still using it instead of an app. Insulet is happily pushing DASH and again a PDM to control the pod. Horizon is build on Dash. PDM = single point of failure not easily replaced. If you have any link beyond late 2018 that shows any indication or further news of development of smartphones controlling the pump functions, it would be greatly appreciated.
