+Enhanced deep link creation requirement
+
+Starting January 1, 2026, all deep links for Power Apps mobile must include the environment ID as a required parameter. For model-driven apps, the app logical name is also required. Existing deep links without these parameters stop working after the deprecation date. Update your links now to avoid disruptions. Until support ends, old links without the environment ID have slower performance. For more information, see Use deep links with the Power Apps mobile app.
