[AG-DEV] AG3 Shared App Migration - EventID

[Susanne Lefvert]

Hello Todd,

Which version of the software are you using? The event.GetSenderId()  
should return the public id of the sender. We did have a bug in the  
software that sounds like the problem you are describing, that  
particular bug was fixed in 3.0.2. If you are running earlier  
versions of the software, I would recommend updating.
