Although the last BlackBerry Beta Zone app update that arrived was noted to include a fix for the 'jumping surveys' bug on Passport devices, that fix apparently didn't work for everyone. As such, a new BlackBerry Beta Zone app update has now been released that once again, includes a fix for that bug.
This time around, rather than using BlackBerry World, you'll have to open the Beta Zone app and update directly from there. Once completed, you Beta Zone app will move from v10.0.0.46 to v10.0.0.50. As noted in the changelog, other changes in this release include minor fixes for the Beta Zone discussion boards. The update is live now, so go ahead and grab it if you haven't already.
