Farm merge
The signs to update I cannot do says it is already upgraded and sign stays how do I either upgrade or get rid of the signs in the game
You can use the upgrade if available then save three cards with one arrow to upgrade to level two, three two arrow cards to upgrade to level three. I've not gotten any extras after upgrading to level three on any of the items. I've also used level one, then level two and finally level three. They give you a few more items when you merge.
