I`m lost, any clue on where to change the Name and Description globally? Either on NetScaler or StoreFront, this is OnPrem and not Citrix Cloud, which do have that option. #CKHRXATV2 I know that this can be done via GPO, but my device is BYOD.

GACS could be a possibility. This is a Storefront setting which is getting pushed at first login/configuration so you would need to reset your CWA. https://developer-docs.citrix.com/en-us/server-integration/global-app-configuration-service/overview.html

There's no supported way to change the store name/description. It might be possible by changing it in the web.config files. You can definitely find it in the roaming/web.config file and it's probably some other config files that would need updating too but changing it is not something that's tested or supported.
