I've had the vision 2+ about 2 weeks now. The first 2 times flying no issues. 3rd time flying had control of camera but no video feed. 4th time couldn't connect at all. Made sure all batteries are fully charged and tried again. Took multiple attempts but did connect. What I noticed was that battery charge showing in the android app first went down to 66%. At this level I could not connect. I kept shutting everything down and trying again and the battery level fell to 33% in about 5 minutes. Now the app always shows 100% charge no matter how long I've been flying. If I always fully charge the extender before flying I have no issues.
