Description:
The Manage Profile page’s username field has a restriction allowing changes only once every 90 days. However, in the process of e2e testing, an issue was discovered where the validation isn't working in some cases.

Reproducing this issue manually is challenging without modifying the source code to override the 90-day restriction. Take the steps below to replicate the issue (not waiting for 90 days to pass).

Prerequisites:

• Update the source code to make the username editable:

1. Navigate to:
   src/components/frame/v5/pages/UserProfilePage/partials/UserAccountPage/hooks.tsx
2. Modify line 31 to:

return { canChangeUsername: true, daysTillUsernameChange: 91 };

Steps to reproduce

1. Log in using Dev Wallet 2 account.
2. Navigate to the Manage Profile page.
3. In the username field, enter a username that is already taken (e.g., “leela”).
4. Observe that the field provides feedback indicating the username is not available.
5. Click the Save Changes button.
6. Click the Save Changes button again.

Scenarios 2

1. Log in using Dev Wallet 2 account.
2. Navigate to the Manage Profile page.
3. In the username field, enter a New username.
4. Observe that the field provides feedback indicating the username is available.
5. Click the Save Changes button.

Expected behaviour

• The system should show the validation message and prevent the username from being updated to an already-taken value.

Actual behaviour

• The username is changed to the already-taken value, bypassing the validation.
