Hi @Antmkjr ,

For your first problem, the new version of the Web connector (currently available in Power BI Desktop) automatically creates a Web.BrowserContents query. Such queries currently only support anonymous authentication. In other words, the new Web connector can't be used to connect to a source that requires non-anonymous authentication. This limitation applies to the Web.BrowserContents function, regardless of the host environment.

For your secend problem, you can actually add a WaitFor parameter that will wait either for the page to load completely or for some html code to load before it grabs the html code. Here are some examples:

// Wait for ten seconds [WaitFor = [Timeout = #duration(0,0,0,10)]]

// Wait for div.foo to appear (with a default 30-second timeout that will throw if div.foo hasn’t shown up yet) [WaitFor = [Selector = "div.foo"]]

// Wait for div.foo to appear with a ten second timeout [WaitFor = [Selector = "div.foo", Timeout = #duration(0,0,0,10)]]
