[Windows Central Question]

My Lumia 520 has updated itself to Cortana, my 925 has not, both phones have 8.1 installed, is there a 925 Cortana problem ?? I`m in the UK.

Isn't Cortana in the UK still in Alpha like in most other regions too? If so, you would need to have both your devices enrolled in the Preview for Developers program. I assume that's true for your 520, but you may have forgotten to do that on your 925.

No but you still need the denim update for the 925 and this update is not released yet for your 925.
For the 520 the denim update is already released and you have it on your 520.
So there is nothing wrong you only need to wait for the 925 update.
