Tbf that seems like the proper response to me.:-)

Normal human ways of thinking go like: however you do it, so long as the job gets done it's fine! ☺️

PM thinking: even if nothing ever gets done, so long as I collect a salary we continue to have 3 hours of meetings most days every week, it's all good! 🤔🤯

Also, afaik, the conflict between the PO and PM roles is somehow literally the point? You get blamed if the tasks don't get done, while the PM ensures that endless reports get generated - I doubt the vast most of which are ever read, and I know that I for one can never find one of those later, in part bc there are so many of them and they encompass everything else into them as well (Jira tickets, Slack messages, hundreds of emails per day mostly saying "this Jira ticket or that Confluence page has been edited", the former of which for the life of me I cannot figure out how to turn off!).

So... not only I but we all feel your pain! Otoh, that seems one of the first job roles that will soon be replaced by AI?
