Great to hear you like the app! 

You should be able to scan any QR code that contains either a lightning address or an invoice. 

The upcoming release, due in a couple of weeks, will include the ability to type/paste as well.  

 I'm currently able to only scan lightning invoices, not addresses. can you help troubleshoot?

super excited about the new update! ⚡
