I’m having the same issue, is not every follower, but quite a few are reporting that the buttons don’t open any links.

I’m also having a similar issue.  I will generate 100-200 comments in a video with the CTA.  When I manually go and check some responses in my DMs, I have non followers say they don’t even have a button to press..

it’s a hard to thing to prove if they just don’t understand the button, or if something is really happening.

Me too. So many followers are saying this. 

Is there any problem with sending the direct link in the first message, without requiring the person to click the button? I'm experiencing significant losses because of this.

Yes! I had the same thought, are they confused or is there no button. I have asked for some to reply with screenshots but haven’t gotten a response yet.
