What did yoko ono do during the 1967-68 recording sessions that the other three beatles (other than john) did not like?

Yoko Ono would offer her own suggestions and opinions about the songs the Beatles were working on.

Yoko Ono was a conceptual artist when she and John Lennon met, and he found her art interesting. They became very close and some blame her for the breakup of the Beatles. As a couple, they moved to New York in the early 1970s, and their son Sean Lennon was born there in 1975.
