Can't share

[dmh]

On yesterday's Zoom I could not share. The error message claimed the host did not allow me, but I am the host! I recently changed the name of my computer from TEST to Denise and since then when I join other Zooms, I the word TEST shows up under my photo. How am I able to explain to Zoom that I am still the same person. The account is under my name as Denise and I never wrote TEST in my account.
