Ok, so when someone comments on my IG post, they get sent a message and the idea is they click the button to confirm they want my freebie and the next step is entering their email. The button to click to confirm they want my freebie was working fine and now it seems it’s not. 

Is there a way to work around this with a comment reply? I’m getting sick of manually sending people and apologising for the messages they got that was pointless.
