Lets try to stay positive regarding our applications. I have read comments obsessing and speculating over our applications being delayed but do remember that all these are unfounded speculations. Nobody can truly say "THIS IS WHAT THE HOME OFFICE IS DOING".
Let's try to focus our energies on other things while we wait. In addition, its not healthy to obsess over these things.
In due time, we will start getting approvals and then pop some champers to celebrate!
Just for info - Home office received my application on 14th April, I have since done the Biometrics on 18th May and I am sitting tight as well.
All the best and please, no obsessing over applications if you can try (except this goes on for 4 months and then I'd get worried
