The internets not very bright is it?

When I want to add to my order on a Walmart app I’m told check my internet,

Everything else is open to me but Walmart is still saying check your internet,

My streaming go to app is tubi,

I have little if any difficulty with it,

Last night when I tried CBS,

I was told you have to have internet to use this,

I have internet I use my smart smartphone,

Why is that not enough?
