[Sword & Shield] LF Help Redeeming Shiny Zacian code

Managed to get Shiny Zacian code from Gamestop Ireland but I only have Sword. Can someone please help? Thanks.

I have Shield and already got them both by trading, I can help you with the code, no problem, pm me and we'll do it

I can send you one first and then you give me the code for me to redeem it, so you see I'm not just scamming

Now I don't want to give too many ideas, but I wonder if VPN-ing works...

you can only redeem the code for the opposite legendary to your game for example if you have sword you can only redeem the shield shiny
