I am experiencing unexpected behavior in Azure Data Factory (ADF)'s data preview while working on a data flow. The data preview continues to show older data even after refreshing it. I have to turn off and turn on the data flow debug to view the updated data. How can I resolve this issue and ensure the data preview reflects the most recent changes immediately?
Furthermore, I am encountering issues during CI/CD pipeline deployment of ADF changes from my developer environment to production:
In some data flows, certain columns on the Sink side are either removed or unselected in the mapping after deployment. During execution, some data flows fail without any clear reason, but when I copy the activities to a newly created pipeline, the issue is resolved and the pipeline runs successfully. How can I troubleshoot these issues?

I think, if your data preview is stuck showing old data even after a refresh, try flipping the Data Flow Debug switch off and on—it’s like giving the system a quick wake-up call to grab the latest stuff. Double-check your source settings too, like the file path or query, to make sure they’re pointing to the right, up-to-date info. You can also tweak the Debug Settings—bump up the row limit or turn off sampling—so it pulls a fresh batch instead of leaning on some dusty cache. If that’s still not cutting it, just close and reopen the data flow editor to wipe the slate clean. Now, about those CI/CD deployment headaches where sink columns go missing or data flows flop for no clear reason: after deploying, peek at the sink mappings in production to ensure nothing got accidentally dropped, and fix them if needed. Dig into the JSON files between your dev and prod setups—maybe in the ARM templates or Git—to spot any sneaky differences messing things up. When a data flow fails, check the Monitoring logs for clues (trust me, they’re gold for figuring out what’s broken). And if copying things to a new pipeline magically works, it might be worth recreating those tricky data flows in dev, testing them like crazy, and redeploying to dodge whatever gremlin’s hiding in the original. Hope this smooths things out for you!

The data preview continues to show older data even after refreshing it.
If your data is not updating once Import the projection as follows:
If you are unable to preview updated data after importing projection, clear your browser cache, caching, data flow and features can cause the issues may cause above issue. Along with that manage Azure Data Factory studio preview experience.
About your CI/CD Pipeline, column mapping and execution failure might be the main issues. For more information you can refer to below documents:
