I have this same issue. I rely on the Apple Health data as an aggregate for ALL my health related apps. One in particular shows inactive in the list of data sources, when I try to edit it will not allow me to select it to active. In the app in question, all data is setup to allow access to apple health. This is my blood pressure app. I don't want to remove it and lose all that data and have to start over. any ideas? There are other apps that have been reinstalled and those face the same issues.
