+## Update availability
+
+After you publish an app update in Partner Center, there can be a short delay between when the package passes certification and when the GetAppAndOptionalStorePackageUpdatesAsync method recognizes that the update is available. Most updates become available within a couple hours, but some publishing and distribution steps may take longer to finish in certain cases.
+
+### Detection frequency
+
+This API limits how often it checks for new updates. When an app calls the method more frequently than the allowed rate, the method returns the last known status instead of performing a new check.
+
+The current limits are:
+
+- No more than one check every 30 minutes.
+- No more than ten checks within any 24-hour period.
+
+If an app exceeds these limits, the method continues returning the previous status until the applicable time window passes.
