A WebmasterWorld thread reports that when you try to login to Google AdSense using your Android device or an iPhone it rendered the reports all weird. I tried to reproduce this on my side, but I am currently not able to.
What many are reporting is that the report seems to load in an iframe below the login box, after you login. Let me quote one of the reports:
I typed my username and password.
The report appeared just at the place where I typed in username and password.
It seems like the report is in a not scrollable IFRAME starting at the position of the input for username and password
I think I am not having the issue because I am logging in automatically. Google AdSenseAdvisor replied to the thread saying:
I'm investigating. I'll let you know when I hear something back. Thanks for flagging this.
We have no ETA for a fix or even a solid confirmation what type of bug this is.
