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 "update_driver_names.zip" 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.

thanks
