If you are experiencing any mobile related issues, eg. access problems, profile update problems, clients submitting reviews from a mobile, etc....
It is very difficult to say exactly what the problem may be, because there are so many devices on the market and not all are compatible with the latest technology..
The best course of action would be that you try from a different mobile device or a laptop or desktop PC instead.
Sorry that we couldn't be of more help, but sometimes these things are out of our scope of control.
