I have a Google Drive app running on BlackBerry 10 and PlayBook devices. The OAuth process was working fine for all users. Suddenly on Aug 23rd I received reports from some users complaining the "Accept" button is disabled and can't complete the authorization. So far I noticed that these users use Spanish and Arabic locale (that's what appear so far from the screenshots and support emails they have sent). For the majority of the users, OAuth is working just fine.
One thing to note, my app is android app running using the BlackBerry Android runtime. When I tried the same code on android devices running android 2.3.3 and 4.0 the process is working just fine and the Accept button is enabled.
On Sep 4th, I retested on android browser on 2.1, 2.2, 2.3.3 simulators, the Accept and Cancel buttons are both disabled.
I'm having same issue on android 2.3.3 android devices. It does not related to language.
Google OAuth login page 'cancel' and 'accept' buttons are not enabled from Aug 22nd
Google engineer replied to my question. It can be expected to be fixed by the end of this week.
