2 major prosites payment issues

2 major things discovered with Pro-Sites on my particular site and paypal:
- Using paypal as the payment processor, Pro-Sites doesn't allow mobile browsers through to the Paypal Checkout! I tried it in mobile versions of Chrome and Firefox. Paypal comes up on desktop browsers just fine (Chrome and Firefox).
- When ever I checkout with Paypal, it always has the same product name in the shopping cart. If I checkout as testsite3, paypal lists it as testsite4. If I check out as testsite5, paypal still gets it as testsite4 that I'm ordering.

I can't seem to figure out why these happen. I opened my site for support.
Thanks!
