you just need change your syntax to use vcs_info in double quoted prompts

prompt="%2/"'${vcs_info_msg_0_}>'

or here is another example (parrot os prompt)

prompt="%F{red}?[%f%F{green}%n%f%F{yellow}?%f%F{cyan}%m%f%F{red}]?[%B%F{magenta}%~%f%F{red}]%f%F{201}"'${vcs_info_msg_0_}'"%f"$'\n'"%F{red}??%f%F{yellow}$%f"

Inside double quotes, the parameter expansion is expanded immediately, so you are hard-coding the value of ${vcs_info_msg_0_} when the prompt string is defined, rather than the value when the prompt is displayed.

Your options include

  1. Continuing to use single quotes

  2. Escaping the $: prompt="%2/ \${vcs_info_msg_0_}> "

  3. Setting prompt itself inside precmd, so that prompt is freshly defined after each update to the VCS information.

     precmd () {
     vcs_info
     prompt="%2/ ${vcs_info_msg_0_}> " 
 }
