If there is a setting i need to change for www.remarpro.com to recognise it, please let me know.
Your WordPress-powered website is not in any way connected to the www.remarpro.com website. There’s simply no link at all.
When I checked your profile earlier, I saw a different address: https://www.innertransformation.co.uk/
which is surely not a WordPress site.
But the link you provided (which is now in your profile) is a WordPress site.
But the app is not able to recognize it as such because XML-RPC, the feature required for this to work, seems to be disabled on the site.
For example, visit this URL with XML-RPC enabled: you’ll see the text “XML-RPC server accepts POST requests only.” https://vecommander-rowa.instawp.xyz/xmlrpc.php
Visiting the equivalent URL on your website gives an error message:
https://www.awakeningsoul.co.uk/xmlrpc.php
This is usually done by your host or a security plugin for security reasons.
You need to have XML-RPC enabled before you can use the mobile app.
