'mDNS_NAME' was not declared in this scope

I'm not a programmer. Please be patient with me. I might be doing something wrong.

I saw you do some changes in the code which deals with mDNS_NAME

After performing a build, I get the following error:

Had to add [#define mDNS_NAME] line in arduino_secrets.h file.

Issue resolved
