Yeah, that happened to me too after an update, I had to reinstall the Xfill app and reset permissions, you can try that first, it fixed it for me right away
Yeah, updates can sometimes mess with Xfill access. If what @Dave Dave said doesnt work for you, you can check for any new permissions or firewall settings that might be blocking it. Sometimes rolling back to an earlier version helps too.
It happens, sometimes the update can reset permissions or disrupt app integration. A good first step is to reinstall the app like @Dave Dave said, check for any pending updates and make sure its properly logged in.
