I turned this off recently because I was experiencing some latency when reading and writing to tags. It fixed the issue and I though my problems were done. Then I noticed that whenever I would navigate to a different project via `system.util.retarget()` or `system.vision.retarget()` any tag bindings would lose connection and same with database connections too. If I launch the desired project directly from the vision client launcher everything behaves as expected. Is there a cache or something I need to clear so I can retarget normally again? I only notice this in vision clients.  
We only have one gateway also.  
I'm running 8.3.4

I filed a ticket with support. They've identified it as bug likely with  
`retarget()`. Tag connections weren't actually affected unless they were done via expressions. All expression bindings would fail after retargets. Just FYI.

Hi,

Could you please provide an update on the status of this ticket? Has this issue been resolved, or is it still under investigation?

We are experiencing the same behavior and would like to know if there is any workaround available.

In our application, we are also using the `system.util.retarget()` function to switch between projects. Please let us know if there are any known limitations, recommendations, or alternative approaches related to this use case.

Thanks in advance for your help.
