Amazing Fields Not Showing or Disappearing
On very rare occasions, there can be a network failure talking to Trello. When this happens, Amazing Fields can run into problems getting data about your cards. Rest assured that your data is still safely stored on Trello's server with the card data.
This can lead to some fields not showing up or the entire Amazing Fields powerup not showing on the board or card details.
Browser Refresh
Normally disappearing fields or other similar strange behavior can this can be solved by simply reloading your browser window.
On some browsers you may need to do a full browser reload to resolve the issue. Hold the Ctrl key while you click on the reload button.
Network Access
Some enterprise networks are setup in such a way that they block the connection to app.amazingpowerups.com. Several customers have reported that Amazing Fields works great at home or on their mobile hotspot but doesn't work well on their work network or some other specific network. If you are seeing something like this it could be network policies blocking access. The way to resolve this is to contact your IT administrators and see if they have any blocking in place.
Powerup Reinstall
I have heard from a few users where the browser refresh didn't work and instead they had to reinstall the powerup. It is not clear what conditions lead to this, but the process is pretty simple.
Click on the "Power-Ups" button on the board, select "settings" for Amazing Fields, then click on "Disable". This will uninstall the powerup. Once you do that, just go back to "Power-Ups", click on Add Power-Ups, and then find Amazing Fields again and add it to the board.
Note: Do not check "Delete Power-Up data" or you will lose your Amazing Fields data. The data is stored on the Trello servers with your cards and it stays around even when you disable the powerup.
Trello Status
You can also check the Trello status page to see if Trello itself is up and running correctly. This site is updated when Trello is experiencing major outages. It doesn't show all the issues that may have occurred, but when there is a big issue it is the best place to confirm.
