Hi there and welcome
What you have to do is first install the Gmail app if you do not already have it.
You can get it from the app store
Once you have it you can then administer your labels within this app n your account
My link below explains all the functionality you can do with organizing your emails with your labels
If you like, I can also call you and walk you through this?
Else, If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
andif you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
