Can I see totals somewhere?
After you’ve set weights to some of your cards, you can see the totals in the Power-Up main menu (click the link “Card Size” on top of the Trello UI). You’ll see a list of individuals with the total amount of work assigned to them. Alternatively, you can choose to view totals per label or per Trello list.

Should I update the estimate as the work progresses?
We don’t suggest updating the card weight based on the work done so far. We advise to updated it only in a case you’ve found out that the work is bigger than initially thought.
There is a separate Spent field, which you can use for inputting the work done so far. If you do so, the remaining work is automatically calculated and shown in your cards.

I have authenticated the Power-Up but now it has disappeared from my board
The likely reason is that someone on your team disabled the Power-Up on your board. If anyone on your team enables it, it will be visible again for all team members. That’s how Power-Ups work, either everyone sees it, or no one sees it.

Why do I get a message “You don’t seem to be a member of a workspace”?
In order to use the Power-Up on your board, the board must have a workspace associated with it. Creating a workspace is easy, just follow these steps to create one.

I added a user to my board but he/she cannot use the Power-up
Each user must authorize the Power-Up by clicking on the Power-Up name on top of the Trello UI and going through the auth flow.
Any person who wants to use this power-up must be a member of the Trello workspace where the board exists. It's not enough to add a user to your Trello board, you need to add that person to your workspace as well.

Why do I get a blank page when trying to authorize with the Trello desktop app?
Auth flow does not work in the desktop app. We are looking for options to have this fixed but meanwhile, the workaround is to use the web app for authorization (after which you can use the Power-Up in the desktop app).

Troubleshooting
Check your internet connection
The Power-Up needs an internet connection to work. If your connection is interrupted or slow, the Power-Up may appear to be working, but it may not be able to update data on your boards. The Power-Up may not recover automatically if you regain the connection after an interruption. Make sure you have a working internet connection.

Reload the page
If your internet connection has been interrupted or slow, that may have an effect on the Power-Up functionality. Once you regain connection, the Power-Up may not recover automatically. Reload the page (Trello board) to make sure that the Power-Up has recovered from interruption.
