You should log into the Samsung members app on your phone. If there is a banner there, you can participate in the One ui 2.0 Beta program. Your SS refers to an older Beta version. The Beta for the Note series is starting to roll out so may not be available yet. If you are tied to a carrier using their own fw, it will not be available
After you register did u use different Samsung account?I bought unlocked note 10+ from Samsung. I've already downloaded the Android 10 Beta. Using it for a few days now. So I have the One UI Beta app but this is what is pops up with. Plus what is "SS"?
