QR codes availability


Does anyone know where or how I can get the QR codes for Forneous F4 I'm DYING for this beyblade. Im in the us .I haven't been playing long .I have 75 on the app but I've been across some I didn't know even existed but I can't find any qr codes for them 😭

Oh and has anyone had any problem with the app not awarding achievments when you know you got them??
