Hello,  
I’m having a small issue with Ignition and MQTT. I have created, in my local server, different data types and the related instances for all the machine. I can easily transmit all the data in the cloud based Server but the received data are incomplete. Some tag of type string are incomplete or missing while I can see them correctly in the local machine.  
I can’t figure out how to fix this issue. I have tried to delete the instances on the data server and refresh the transmission but I still have the same problem. The string tags are not correctly updated.  
Any suggestion?  
Thank you
