A. 1. Check your device's performance. Close any unnecessary apps running in the background to free up resources. 2. Lower the brush size and complexity in the settings to see if that improves responsiveness. 3. Adjust the performance settings in Adobe Fresco. Go to the app settings and look for performance options to optimize for speed. 4. If using a stylus, ensure it is charged and functioning properly, as a low battery can affect performance.

B. 5. Try using a different brush or tool to see if the lag persists. Some brushes may be more resource-intensive than others.
