Sponsership changes in 2019?

I may be wrong, but I don't think anyone has mentioned Sandgren's sponsorship change to "Letour"... I tried inserting a picture, but I don't know how
I think Bencic may not be sponsored by Nike anymore... she wasn't wearing the most recent kit, apparel or shoes..

Edit: I hadn't seen any of her matches until a short match point snippet tonight.
