#Apple have enabled "#AdvancedDataProtection" (encrypting users' #iCloud server-side) in the UK. Update your device(s) to the latest version, and enable it.
The UK have significant powers under the #InvestigatoryPowersAct (& future #OnlineSafetyBill) to halt this rollout (or attempt to undo it, but that's harder) — so it's really worth enabling ASAP.
