Well, it gets released when it's ready.
So, apparently it's not ready yet. Do you want to have an update that was not ready brick your phone, just to keep a fixed release date?
An update will come when it will come. I do not understand why anyone would get so worked out about it.
1. Because my Jolla is not working correctly
2. Because I bought into the marketing promise at the outset
3. Because it is just another failed promise
4. Because comms through Jolla channels is terrible
Other than that I am pretty ambivalent now. It comes when it comes and my Jolla will sit patiently in a drawer.
Actually looking at the release schedule this one is 9, 10 and 11 as July release took the August date number.
