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.

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.

1. Click on the Power-Up in Trello main menu.

2. Select Remove Personal Settings.

3. Click Clear Data (removes the auth token only).

4. Click Board button and authorize the Power-UP.

5. See if your issue is resolved.

Some browser extensions may interface with the Power-Up functionality. Log out from Trello. Disable all or some browser extensions and log in to Trello again. If you disabled your extensions and the Power-Up started working normally again, one of your extensions is likely causing issues with the Power-Up. You can now re-enable your extensions one by one until you find the problematic one.

If it's a privacy extension you want to keep using, such as DuckDuckGo, Ublock, or similar ones, try adding the following domains to your allow list:

screenful.com
app.screenful.me

Trello can't support every version of every browser, so it helps to make sure you're using one that's supported and tested by Trello.

Next, try logging into Trello in the following ways to see if you can reproduce the issue you are having:

1. Try using a different browser on the same computer

2. Try using a different computer

3. Allow cookies from third party sites in case you're running into any issues with linking to GoogleDrive or Dropbox

If you can't get another browser to try, we'll need you to clear your cache and check for errors. Here are simple instructions on how to do that:

• Instructions for Firefox

• Instructions for Chrome (You only need to check "Empty the cache" and "Clear data from hosted apps".)

If nothing above helps, in Edge, Firefox, or Chrome you can check for errors with the Error Console. 

To do that, open the board in question and use:

On Windows:

• F12 in Edge and go to the Console tab.

• Ctrl + Shift + J in Firefox or Chrome for Windows.

On macOS:

• command + option + J in Chrome

• command + shift + J in Firefox

You can copy any errors you see there, or take a screenshot and send it to us.
