Just going to throw this out there. I don't know if it's my phone or the site but see attached and wasn't able to open. Was stuck. Basically had to to a reboot and was able to open. Samsung, please fix your updates, it's getting worse as time goes on. More issues today then months ago.
Go to Settings > Apps > Find the Samsung Members app > Storage > Clear Data. And that should fixed it. This also applies on some apps that has same situation.
Note : Some app may requires account and after clearing data you'll need to sign in again to continue
