@Scoper I am following as I purchased a KL130b in the UK this week and cannot connect it to its wifi - so I can't set it up - and then the app decided it too was going to die. Not amused, as they aren't the cheapest bulbs out there and if I had known that this one was going to be such a problem I would have looked for an alternative. 

Seriously, what with this and the app resetting itself I am left wholly unamused and very frustrated at wasted money!

  @Raye you didn't happen to buy off an eBay seller in Southall at a really good price? Is it possible they sold us defective or fake product?

At this point, I'm tempted to take them all out and replace with a different product.

  @Scoper 

Nope, I purchased mine from Amazon. So was hoping it was official.

  @Solla-topee  the app is so up to date it wiped the data of both my other Kasa bulbs. I have sent the bulb back now and am replacing the other two with Lifx ones. I tried all of the resolutions on the site multiple times and none of them worked, hence sending the bulb back.
