There shouldn't be any issues capturing screenshot via power key + vol or palm to swipe if enabled. Although some apps may restrict taking a screenshot of the app, it is limited to app and not entire system.
If you are not able to capture on all apps, Please send us an error report from the Samsung memberās app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
