Hi, 

Just tried to launch Bravia Core to see if there was any new content, but it wouldn't launch. I get an error saying Widevine Level error: Your device is not compatible with this application.

I did some digging as I'd no idea what Widevine was. Turns out it's some DRM suite used to confirm that the device is in compliance with HD DRM. I'm guessing Bravia Core requires L1, but according to an app I downloaded just to check, my device is now L3.

Another google suggests this happens to people when they root their phone, however I have never rooted my phone, it is still under extended warranty and insured. 

I suspect one of the updates broke something. Any chance of a fix?
