Hi @brocaar i have been testing with the latest loraserver and have come across this issue when using confirmed messaging
I have a device that is sending confirmed messages and it was working with the older setup before changing to the latest after chirpstack announcement
The first few message maybe 2-3 messages are always confirmed up but after that it changes to being unconfirmed data up.
The only thing that has changed is the lora server.
I have not changed anything on the device since moving from the older version of the loraserver
On the older version of the loraserver it always sent confirmed up messages
I just spun up the old vm running the old loraserver and here is the output it is always confirmed data up
