It's my first time using the app. I scanned the QR code, but I'm not sure if I succeeded or lost the connection. What I do know is that the QR code is single-use.

i think you succeeded, i sent you a message on SimpleX - at least i think it's you :-)

Yes, I received your message, but I get an error when trying to reply: chatCmdError.. 1 agent cONN SIMPLEX..

Try closing and reopening the app

I left you this invitation; let's see if it works this way.

Great, here is a one-time anonymous invitation which should add me to your contacts or send a message, after you've created a user for yourself.
