Webpage is not updated in XIBO

Hello ,

Please note that we are using IIS in windows player with XIBO application , when we do an update for the webpage , its not reflecting in xibo , and every time we need to uninstall xibo and install it again , we tried to re-assign the schedule , also purge all but its seem that content is cached somewhere even we are using edge whitelist and we tried also to clear cache for edge browser .

Is there any solution ?
