When subscribed to data changes and then read a value from the OPC-UA server, it will continue to receive subscribed data even if its value has not changed

[anganing]

Describe the bug
When subscribed to data changes and then read a value from the OPC-UA server, it will continue to receive subscribed data even if its value has not changed. opc-ua server is s7-1200.

Expected behavior
I only want to receive a subscription when the value changes

Logs and Packet Captures
As long as I annotate this line to read the code, there will be no problem, but I must read the data when subscribing to data changes

Additional context
Version of Eclipse Milo you are using 0.6.3/0.6.11/0.6.10 all try. opc-ua server is simens s7-1200

I am not able to reproduce this with an S7-1200.

You'll have to provide a Wireshark capture or otherwise prove it's not your code or the server at fault.
