Android App Recent Update Feedback

There appears to be a dimmed screen surround on the new android update (June 2022). It now makes the portrait screen view very small as only the middle of the screen is visible particularly when viewing the alerts and most of the time I can’t work out what has set the alert off. If this is an new ‘improvement’ can we please have a button to switch it off and revert back to original as it is a step backwards in my opinion.
