The product formerly known as Flow from Microsoft. This thing is powerful, but the interface is so bad - edit an expression, click update, and sometimes it doesn’t update. A part of a loop fails, you cancel the run, and you don’t know what’s wrong! The whole run has to finish before you can see what went wrong. When processing large spreadsheets or Sharepoint lists, that may mean a lengthy wait.
There is no debug console to check the output as a flow runs, so have resorted to writing files to OneDrive so I can check the output.
For someone who usually writes in C# in Visual Studio, Power Automate is rather frustrating and not a very mature product.
Mini rant over.
