Links not appearing in website

We have a SquareSpace website that contains a group of social media links at the bottom.

The code for this block is:-

<hr>
<div class="sqs-block-content text-align-center"><h1>Share</h1>
<p><a target="_blank" href="https://www.facebook.com/sharer/sharer.php?u=http%3A//nataal.com/mrcy">Facebook</a><br />
<a target="_blank" href="https://twitter.com/home?status=http%3A//nataal.com/mrcy">Twitter</a><br />
<a target="_blank" href="https://www.linkedin.com/shareArticle?mini=true&url=http%3A//nataal.com/mrcy&title=MRCY&summary=Talking%20to%20Barney%20Lister%20and%20Kojo%20Degraft-Johnson%20at%20Glastonbury%20Festival%20about%20dancing%20into%20the%20light&source=">LinkedIn</a><br />
<a href="mailto:?&subject=MRCY&body=https%3A//nataal.com/mrcy">Email</a></p>
</div>

Twitter and the email link show, Facebook and Linkedin are blank lines. This is true of all 1000 odd pages in the site. Other browsers, Chrome and Edge for example, show all 4 lines.

This is a new phenomenon in the last 48 hours or so.

What I see, do you have any custom rules/lists in brave://adblock ?

I have not customised Brave nor added any new adblock type extensions / rules.

I’m using all the standard settings “out of the box”.

This problem appeared suddenly overnight about 2 days ago. Maybe one of the overnight builds is causing it?

The Facebook link at the bottom of https://brave.com/privacy/website/ for example, is visible.
