I know that Lists are getting lots of attention in last cca 2 years.
As for us, we are sampling Planner to PowerBI on a daily basis. So we know, if some item was modified or not. We have also added the due date to the checklist, and parsing it out using Flow, when put into the PBI report: Checklist item 1 (14.2.2022)
By having it sampled on a daily basis, we can track the changes. So in our PBI report, we've introduced the Delta field of the following format: 3x, 3 months - so you know, the task was shifted 3 times already and the delay is 3 months.
So, that's why I don't agree with the table statements, like the lack of PBI support. It is quite easy to achieve anyway, while maybe not out of the box.
Planner has a list support, though only in terms of the Teams component. I agree, that the situation is a bit messy.
Our users are also used to comment on tasks (projects), using a smart phone. This is so essential to us, that missing List app on an Android is a show stopper in itself to us ...
It is a pity that Planner is heavily under-developed and the team introducing things like background, confetti and similar nonsense, has to be felt like an insult to us.
