Thanks Michael.
I fired off the same question to the theme folk and it’s indeed coming directly from the theme. For any who need assistance, these were the steps I followed to make the changes.
You will need to make customization inside Onesocial / template-parts / site-register.php
Copy this file and paste inside Onesocial-child / template-parts (you’ll need to create ‘template-parts’ folder if doesn’t exist already)
Replace
<p class=”express”><?php _e( ‘To finish activating your account, check your inbox for our Welcome message and confirm your email address.’, ‘onesocial’ ); ?></p>
with
<p class=”express”><?php _e( ‘ YOUR MESSAGE .’, ‘onesocial’ ); ?></p>
