Hi Vitor,
one question please:

When I zap from my WoS to an WoS from another Nostrich my Zap doesn't show up in the chat. It's no difference if I zap normal (push ⚡ once) or doubletap the Zap -Button for sending a public Zap with message.

When I zap from my WoS for example an user who uses LNTipBot or Alby it works fine.

The issue occurred since one or two weeks.

Don't know why.

Any ideas 😊🙏. 

 So I zapped you for testing and it works fine with your wallet too.

Only from WoS to WoS it doesn't show up in the Chat. Really strange isn't it?
