Every time I click on a card I get the following error:
Power-Up Loading Failed
Your current browser settings prevent Trello from initializing power-ups.
Trello uses the browser to store local authorization settings. Your browser's current settings deny this access.
To continue using Trello power-ups, please follow the instructions for enabling localStorage access. If you need further assistance please contact support@amazingpowerups.com.
I followed the advice in the link provided. Since I have cookies blocked I added a special exception for [*.]trello.services
But I continue to get the error. Do I need to close all instances of the browser and restart?
