The 'verified' middleware isn't working on my routes

When I use the 'verified' middleware on a route group, it doesn't work - but when I use it in kernel.php's $middleware variable it does.

My routes/api.php file:

<?php

use App\Http\Controllers\V1\AccountController;
use App\Http\Controllers\V1\AccountFeeController;
use App\Http\Controllers\V1\AccountTypeController;
use App\Http\Controllers\V1\AuthController;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

/*

*/

Route::middleware(['auth:sanctum'])->get('/user', function (Request $request) {
    return $request->user();
});

Auth::routes(['verify' => true]);

Route::prefix('v1')->group(function () {
    Route::middleware(['auth:sanctum', 'verified'])->group(function () {
        Route::apiResources([
            'account' => AccountController::class,
        ]);
    });

    // Auth / user
    Route::post('/user/register', [AuthController::class, 'register']);
    Route::post('/user/login', [AuthController::class, 'login']);
});

I used the breeze starter kit to get started
