Canon SX220. It did work, no hardware changes, but now it doesn't, and there was an app update.
I use the same phone, card, and camera quite often when I travel and this is the first time video won't upload through app to phone (pics still do). I setup on my iPad as well and didn't work either.
Based on this, it's a bug in the app, not a hardware issue.
I hope they fix it or the card and app aren't worth it anymore.
