Hello @SweetnessBlu ,
Thank you for your feedback. If you haven’t already, Please update Samsung members app to latest version from galaxy store and send us an error report immediately after experiencing the issue from the Samsung member’s app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
Few of our beta members also experience network related issue on T-Mobile recently. It may be helpful to reach out to carrier for support too.
