element not interactable on Amazon.com

I'm doing a very simple test for an interview and I can't click the "Start here" link, the error is element not interactable

Here is the following code:

Click Link xpath=//a[contains(text(),'Comece aqui.')]

Its a pretty straightforward element but still I cannot interact, inspecting the element I have:

<a href="https://www.amazon.com.br/ap/register?openid.pape.max_auth_age=0&amp;openid.return_to=https%3A%2F%2Fwww.amazon.com.br%2F%3F_encoding%3DUTF8%26ref_%3Dnav_newcust&amp;openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&amp;openid.assoc_handle=brflex&amp;openid.mode=checkid_setup&amp;openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&amp;openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&amp;" rel="nofollow" class="nav-a">Comece aqui.</a>

Any guesses?

Edit: here is my entire test

There is a couple of elements very similar in the page.

The first one:

You can find it with this xpath:

(//a[text()='Comece aqui.'])[1]

The second one
