Link gw1 to gw2
I found this set of instructions. It’s old but it should still be the same.
Read it and see if you are doing anything different.
I did that, then i get forwarded to a page to log into my gw2 account, even though im already loged in. Where can i see if the accounts are linked?
Possibly they are already linked then? Do you have a HoM stone? You can go there and talk to the NPC to see if your rewards are available.
If that doesn’t work, you should contact support.
