As the problem involves a 3rd party app, we will not be able to debug the issue. It would be best to contact app developer for support. However, if you do experience issue with a Samsung app, please send us an error report with a video recording and we would be able to debug the issue.
Also, software is not certified by Google yet, so Google Pay and other secure services may not work. We apologize for the inconvenience and appreicate you taking part in reporting these issues.
