I used to have an app on my Galaxy A32 4g called Samsung Boost with a few perks I never redeemed but now that app has disappeared and I never got to redeem my perks
Samsung boost is installed now on your new device after first setup or a factory reset. I can not find the app available to download in galaxy or play store. But if it's any help, here is the link to the website boost. https://www.samsung.com/uk/boost/
I think most of the things from boost are now in the discovery tab in your Samsung members app under benefits that's where I got my Disney+ and earbuds etc? Hope this helps
