Azure Data Factory - Data Flow - Join- Broadcast

Question

On 30th April 2020, Azure Data Factory Data Flows show a new option on the Optimize Tab of the Join Activity in the Data Flow. I get a validation error on the pipeline that atleast one side should be a part of the Broadcast. When I fixed the validation issues and published the data factory all of the data flows have broken. Please find attached the snapshot. enter image description here

Answer 1

Problem was resolved next day 5/1/2020. We tried using Edge as well as Chrome with same results, so thinking not cache. Next day everything was working again.

Answer 2

Can you please clear your browser cache and reload your pipeline? There are some updated libraries that seem to have put your browser into an incomplete state.
