AUTO save is not working on charts

Hi @RPEASHWAR welcome to the community.
The saved chart layouts can be accessed from the Angel One web and mobile apps. These saved layouts do not get cleared even if you clear the cache from your device or switch between TradingView or ChartIQ. Our team is working on a solution to ensure that the layouts that are not saved by you get sync’d between multiple devices and they don’t get cleared when you clear the device cache.
