I have the same issue, but only in Firefox 78.0.1
In Chrome everything is working fine.

Thanks for the reply,

Unfortunately this was not the solution for my problem. Tried several different numbers for the max entry. Sometimes it worked, sometimes it didn’t. So I have no clue.

Can’t the sitemap be save to a file using a cronjob and called by the same url?

So this should be:

function wp_mail_smtp_add_cat( $body, $mailer ) {
	$body['categories'] = array('cat1', 'cat2');
	return $body;
}
add_filter( 'wp_mail_smtp_providers_mailer_get_body', 'wp_mail_smtp_add_cat', 10, 2 );

Quick note, I’ve tried some stuff with filters like; ws_add_site_header and wp_mail_smtp_providers_mailer_get_body
