Took me ages to persuade my current manager to use Trello (based on this article https://community.uservoice.com/blog/trello-google-docs-prod...). Finally his response was "OK you win" sigh

Of note just because they use a pm tool, if they like keeping things close to their chest you can end up with a drip feed affect, with them only adding things to the tool when they think you are ready for new work.

This can then cause issues where the work they released needs further requirements capture....
