Shared access problem

Hello. So I’ve made a project that allows opening a garage door. I’ve made it for my father so he uses his own Blynk account. I would also like to have acces to this project without having to change accounts all the time. He shared the QR code with me bur it doesn’t work. If I’m logged in and scan the QR it asks me to log out. When I log out it says the app is stopped by the author… any ideas?

Whose account was the project created under?


My father’s account. The issue was not pressing the play button in his app. However, I am not able to switch between my account and the shared app. Is there amy way to scan the app from my account so I have the shared app in my projects?
