I'm getting an error using LoginWithCustomID using SystemInfo.deviceUniqueIdentifier as uid.
The error message is:
Could not resolve host: {titleID}{Production Environment Url}
where title ID and Production Environment url are the ones set in PlayFabSharedSettings.
The title ID is taken from playfab dashboard project settings, while the Production Environment Url is the default value i've found in the PlayFabSharedSettings (2e706c61796661626170692e636f6d)
I get the error when executing the game on a windows machine I use at work (could it be a firewall related issue?) while I'm not getting it when executing on the macbook I use at home.
