Use the android app, no pin required https://play.google.com/store/apps/details?id=social.snort.app
Discussion
Thank you very much, but I have tried the app and I get the same thing, the PIN is necessary. Attached image.
After this, I have been trying different browsers (Chrome, Opera...) and I have gotten the same error, until finally I tried Brave, which asked me to enter the PIN but finally it worked.
On the android app the pin is ignored just enter anything
