Since people already were making up stories here about David's absence lately:

David on Instagram:

To all BonJovi fans !! Enjoy our new album ! If you are wondering where I was for TV promo ....I couldn’t do all the promotion for 2020 because I was filming my musical DIANA for Netflix. I can’t wait to get back on stage with my band brothers and Rock the world again !! ����������

Oh.. and btw: Bon Jovi was sharing his post in their story congrating him on his success with his musical, and telling that he was missed!
Hopefully all these senseless speculations and making up rumours are coming to an end now...
