We didn’t mention the last update to BlackBerry Maps because it caused issues on my device. Since then I have found that version 10.1.0.805 that was supposed to fix defects and improve performance actually did the exact opposite for MANY people. Many users found that the app would crash immediately upon launching it. Dan let me know about a fix spotted by fbf2012 on CrackBerry to downgrade the version of BlackBerry Maps if you updated. BlackBerry has downgraded the version available in BlackBerry World to 10.1.0.790 and you can install it through your desktop browser.
Kudos to fbf2012 and Dan on this one!
