I am checking the grammar for my app and I find myself being unclear on which of those two I should use.
The original sentence runs as follows:
Once you start using your card, all purchase activity will be displayed here.
I have conducted some research, and it looks as if either could be used.
Is there a difference between the two? If so, which one would be more appropriate and/or grammatically correct, for my app?
I would greatly appreciate any and all replies.
