I agree. It's all about social media right now and she need to get with the times. Use it for work and for us fans to get to know her a little better.
She doesn't have to take million selfies, but she can post her work, backstage photos, throwbacks (I'm sure she has so many beautiful pics), she travels a lot for work (this year alone she went to Cuba, Dubai, Cannes, London...) and she never shares any pics of these amazing places... I like pictures with her daughters but they are usually in bad quality (!?!?)... and she can still post all the boxing selfies she loves, quotes and nail pics she likes, but just to find a balance and post regularly. I hope next year her PR team starts doing better work.
For me Rosie has the best insta, she posts really great pics and a great combination of her work and personal life. I wish Adriana's instagram is more like that...
