BlackBerry has just released another update v 291.0.1.85 for iOS devices today to squash the issues that user were experiencing with the first update. This update no longer makes you login again to BBM, but I have noticed that my personal chats are now gone, although my group chats are all accounted for. Sigh...
Hopefully BlackBerry can get a hold on these updates moving forward so that we don't lose any more important information. As well, when you first open the app after updating, give it a few minutes to propagate and catch up. Otherwise you'll be disappointed with the initial lag.
I think it's time to kill the bloatware called BBM Channels. Anyone?
Let us know in the comments if you are still experiencing any issues with this latest update.
