It was only yesterday that we saw a welcome update for WhatsApp Messenger drop for BlackBerry 10 users. However, the word on the street it that some folk who are running OS versions below 10.2 may not now be able to open the application.

The following hit my email inbox overnight:

"We have discovered an issue that affects users on OS 10.0 and early versions of 10.1 that will prevent WhatsApp 2.11.604 from launching.  We've already submitted a fix to BlackBerry World, which we hope will be approved shortly. Once available, this fixed version will appear as so look for 2.11.605.  Newer OS versions are unaffected by this issue."

Now I'm not 100% sure of the accuracy of the above as I'm running 10.2.1, so if you have been having problems let us know in the comments.

At least the fix is due imminently. Thanks for the tip Derek
