Check which version you have on your mobile device. I was having the same issues on my Blackberry Q10, but I thought it had more to do with the "Android Lite" that BB runs. I found an update to .122 was available just a little while ago. Once I removed the Google Play Services dependency (often a requirement for android apps on BB), and reinstalled the upgrade, it connected immediately!
And it DOES keep track of where you left off, if you tap the correct button. Just tried it out.
