Delete the cache and data from the samsung members app via app settings. Once you've done that restart your phone and then open the Samsung members app and register again. Wait a few minutes then check you software update via settings and it should give you the option to download the software. If you still dont get the update restart your phone then check your software again. Side note to make sure your Samsung account has the appropriate region too. This worked for me earlier so I hope it helps 👍
Hey guys, i got the Note 10+ unlocked USA variant. I went into Google Playstore and actually uninstalled the Samsung Members app and reinstalled and then registered. I had to check for the update a few times after and it took maybe about 4 to 5 mins to register for the update but it worked? Try it out and lemme know!
