Hi,
I am using MS on an Android, and I like this App very much
So I recommended MS to a friend, who wants to use it on a Windows Convertible Laptop, an she has allready installed the trial version
But there is a problem, we wanted to have cleared, before she buys the full version.
If PDF-Files are zoomed in, they look blured, not sharp.
The same file on the same laptop, zoomed in with the standard PDF-Reader is sharp.
The same file on my Android device zoomed in in MS is also sharp.

Question:
Is this a restriction of the trial version? Or is this a specific problem of MS on Windows or on this Device?
If so, how can we solve it?

Thanks for checking,
Jonny
