The Wallets page allows you to see your Exchanges and wallets in detail, add new ones, update your data, or copy your wallets’ addresses directly.
When you have a yellow circle next to the Wallet name, it indicates things don’t make sense, so please follow the instructions appearing in your Exchange tab.
Click on the colored button to show where the issue is. It can help you identify better funds that you’re missing (but be aware, that "auto fixing" those is most likely not the way to go. Only use this for small amounts).
