From Official site:
The Queen has ruled for longer than any other Monarch in British history, becoming a much loved and respected figure across the globe. Her extraordinary reign has seen her travel more widely than any other monarch, undertaking many historic overseas visits. Known for her sense of duty and her devotion to a life of service, she has been an important figurehead for the UK and the Commonwealth during times of enormous social change.
Her Majesty continues to carry out a full programme of engagements, from visits to charities and schools, to hosting visiting Heads of State, to leading the nation in Remembrance and celebratory events - all supported by other members of the Royal Family.
The Queen sees public and voluntary service as one of the most important elements of her work. The Queen has links - as Royal Patron or President - with over 600 charities, military associations, professional bodies and public service organisations. These vary from well-established international charities to smaller bodies working in a specialist area or on a local basis only.

As announced in January, The Duke and Duchess have stepped back as senior members of The Royal Family. They are balancing their time between the United Kingdom and North America, continuing to honour their duty to The Queen, the Commonwealth, and their patronages. Frogmore Cottage in the UK remains their family home.
The Duchess will continue to support a number of charitable causes and organisations which reflect the issues with which she has long been associated including the arts, access to education, support for women and animal welfare.
The Duchess’ official titles are The Duchess of Sussex, Countess of Dumbarton and Baroness Kilkeel.
