Chat & background general questions

Hello,

Been a Zoom user for years & I never take the time to ask these two questions:

1). In a regular Zoom meeting,  e.g. if someone types in the name of a book, I am unable to copy & paste  elsewhere. (I read some earlier comments about this & I am upgraded & not in Webinar mode).

2).  The backgrounds that I have saved in my account so not seem to match when I enter Zoom from different invitation links.  They stay consistent in my account if I generate a meeting but when I join someone else's the few backgrounds I have saved are not always available & I don't know why.  I'd like to have access to all the saved images to alternate as needed.

Thanks
