Problems registering set?

Anyone having problems registering set for points? Signed up last month to insider, got the app, added my first set to collection and registered it for 20 points, all good. Went to app today to add/register my other sets. Link in app sent me to website (using iPhone) hit ‘register’, allowed camera use, scan QR and I get a popup saying ‘add for 20 points but there’s nothing on popup to do so! There’s a bunch of text and a clickable TOS link. What am I doing wrong??
