Issue Summary

When opening a third-party power-up on the Trello Windows app, it requires you to connect to the power-up, and the Power-Up screen within the app goes blank.

Steps to Reproduce

1. Add a third-party Power-Up to your board
2. Open the Power-Up

Expected Results

You can allow the power-up, following the normal flow. The App should then display the power-up accordingly.

Actual Results

The app redirects you to the browser, and then returns a blank screen where the Power-Up pop-up should be.

Workaround

While the team is investigating the issue, the best solution is to use Trello on the browser to access third-party power-ups consistently.
