Norton mobile security premium not showing

I’ve got Norton security and anti virus and supposed to have Norton mobile security on my Android phone. But, yet again, my phone isn’t registering that I’ve got premium service.
When I tried to put in product key, I get an error saying that key isn’t registering or having trouble registering. And I can’t get it to quit acting up this time.
Last time I just uninstalled it and did a reinstall. That’s not working this time.
Any suggestions?!?!
