I can go through the power ups authorizing process

[Francisco Osuna]

Dear everyone, 

I am trying to install a few power-ups on my Trello board, but when I click on Authorize the process gets stuck and nothing loads up. What can I do?

I have seen some people run into trouble authorizing due to their security / cookie settings.  See: https://support.atlassian.com/trello/docs/enabling-localstorage/

You may want to try loosening your browser security settings temporarily and see if that allows you to authorize the powerup.  If it does, then you can look into what needs to be changes to keep that working.

Hello,
What is your user type on the board? Are you a board admin, normal member or observer?
