It means that the app does not know some of the specific details of the token (eg. name, image, decimal number).
All the details about the token are not verified by the Eidoo team.
So, to be able to correctly visualize the token, execute the following operations:
1. Click on the line of the token from “your assets” list;
2. Click on the “i” icon that you can find in the heading;
3. Verify that the token address is the right address provided from the token issuer;
4. Verify or change the details of the token: name, symbol, number of decimals; the right value for “number of decimals” must be the same provided by the token issuer;
5. Confirm the data.
