Is there any need to update the driver names on the Android app anymore?

I have followed the instructions in the document linked on the Play Store, and downloaded the "" files onto my android device, but opening the CrewChief app (2.0.10 Full (build 85)) does not indicate any attempt to unpack/add these names, and clicking on "Show current opponent names" returns a message of "None loaded".

Just wanted to check if this was old functionality and the names can no longer be updated, or if it might be a file name or permissions issue.
