Although it took a little longer then what I'm sure most of us would have preferred, Motorola has now issued a fix for anyone who has been experiencing banking applications not working on their Motorola Atrix. The issue arose shortly after the 4.1.83 update was released and while it didn't affect all banking applications, it did affect quite a few.
In order to get things up and running again, you can now grab the Atrix Certificate Updater from the Android Market. Keep in mind though, the updater only works of you're on software version 4.1.83 but that shouldn't be a problem considering anyone having the issue would have had to of installed that update.
