I have quite a few issues after the latest update with july fixes.
It seems to revolve around bluetooth.
I have a Danalock door lock, and a "Dog & Bone" padlock, as well as an alpine car radio.
I've had a lot of issues with the lock, to get the Dog & Bone padlock to work, I had to restart the phone, and to get music streamed via bluetooth to the alpine car radio, I had to restart again.
I didn't see all these issues before the upgrade.
