Cannot clone git from Azure DevOps using PAT

I have had success using PAT like this;

1. copy clone url for your repository e.g. git clone https://<domain>.visualstudio.com/<domain>/_git/<repository>
2. After you have copied you PAT use as;

git clone https://<PAT>@<domain>.visualstudio.com/<domain>/_git/<repository>

No Username nor password should be required as the PAT should suffice.
