I have installed .29 to my 830 with normal update as well. No issues with the apps update on store.
In general it seems to be a little bit faster than previous SW build with less loading and resuming screens.
But I still get sporadic reboots on 830, maybe one every 1-2 days. I have read that these reboots will be solved when official, per mobile model, SW comes out, i.e. official 830 update SW that will include the correct drivers for every device.
Lets see what's next.
Hopefully MSFT will also release new updates for their native apps to make it also faster and more reliable.
