Unable to Access Brave Rewards

Although I have an Uphold account, Brave’s browser does not allow me to interact with it in any way. This means that all of the options - add funds, withdraw funds, verify wallet, etc. - are dead and do not take me to any feature.

Please identify what, if any, solutions exist. As you can imagine, the purpose of using Brave’s browser is the reward system. If this rewards system is inaccessible, there is no basis for continuing to use the browser.
