Good morning, I hope you can give me a hand with this. I'm doing a couple of power-up integrations to link our trello with another program. All a success. The issue is that I want to go a little further, I want to give my clients a QR code, we did it, everything was fine, the problem is that if the client leaves that card, they can see my entire work board. I checked if it could be a security issue and did the settings but the same thing keeps happening. Is there a setting that I might be skipping?
