I am going to remove some dashboards from an app in production. I update the correct solution in DEV via Power Apps, remove the mentioned dashboards, and publish the changes to DEV. When I open DEV, I see that the dashboards have been removed from the app. Then I deploy the solution to PROD, and it seems to go fine. However, the dashboards are still present in PROD. I have tried clearing the cache, etc., but the dashboards are still accessible. Why are they not being removed?
