I have not been able to download any new apps from Google Play since I have flashed the ICS leak last week. I noticed it yesterday when I tried downloading Notification Toggle. It will go through to the permissions screen, then I get a popup with the message "Error processing purchase. [DF-BPA-09]"
I was able to eventually d/l Notification Toggle by clearing the cache and data for Google Play, but that doesn't work anymore. Has anyone else seen this problem? Were you able to fix it?
