I think they now allowed to use expired BRPs for a few months post 1st Jan.
From HO website: "You may be able to use your expired BRP to travel to the UK until 31 March 2025 if both: your BRP expires on or after 31 December 2024. you still have permission to stay in the UK."
That's not true. My freshly printed passport was denied by a computer at the UK border, they ran forensic checks for 2 hours while I waited in detention and then it was all good and they let me go.
8 years at Meta, worked in AR/VR/Spark stack and mobile/desktop/xplat apps like Instagram for iOS, macOS apps (Origami), comprehensive list @ https://kurilo.org/facebook-work/.
Before that at MSQRD (acq. by Meta in '15) and Toggl.com. Solo-built my own iOS apps with revenue, advised several startups. Know AR/VR and healthcare sector well.
It's a very sensitive topic for the health data! Too many apps sending data left and right, 23andme scandal.. very few apps (e.g. Carrot Care on iOS) adopt such great philosophy.
