     Key Features:
     - Compatible with both Widevine and PlayReady DRM schemes
     - Intelligent caching that compares required vs. available keys
+    - Optimized caching for L1/L2 devices (leverages API auto-optimization)
     - Automatic key combination for mixed cache/license scenarios
     - Seamless fallback to license requests when keys are missing
 
     Intelligent Caching System:
     1. DRM classes (PlayReady/Widevine) provide required KIDs via set_required_kids()
     2. get_license_challenge() first checks for cached keys
-    3. If cached keys satisfy requirements, returns empty challenge (no license needed)
-    4. If keys are missing, makes targeted license request for remaining keys
-    5. parse_license() combines cached and license keys intelligently
+    3. For L1/L2 devices, always attempts cached keys first (API optimized)
+    4. If cached keys satisfy requirements, returns empty challenge (no license needed)
+    5. If keys are missing, makes targeted license request for remaining keys
+    6. parse_license() combines cached and license keys intelligently

         The intelligent caching works as follows:
+        - For L1/L2 devices: Always prioritizes cached keys (API automatically optimizes)
+        - For other devices: Uses cache retry logic based on session state
         - With required KIDs set: Only requests license for missing keys
