Row Level Security not allowing new entries

If you are really desperate, this appears to work.

Once you've navigated to the RLS view, append the URL in the browser with 

?unmin=1

This will force rendering of the full JS instead of the minified version.

Using your browser Dev Tools (F12 to open for Chrome/Edge), navigate to the Sources (Chrome) or Debugger (Edge) tab.

Following the script hierarchy, open:

app.powerbi.com / 13.x.x.x / externals / ngTagsInput.js

Find line 259 and set a breakpoint - the line should read:

if ($scope.tags.length >= $scope.options.maxTags)

Go back to your browser and refresh the page which should trigger your breakpoint.

Use the JS Console to run this command:

$scope.tags = []

You can now resume the script execution by pressing the resume (play) button.

You should now be able to manage RLS. You will need to repeat these steps again as you navigate to additional datasets.

Have fun!
