I am creating an app to track time associated with Microsoft Planner tasks. I have galleries set up to show all office 365 groups that the user is a member of and then show all plans in the group selected from the gallery. That all seems to work fine. However, when a user clicks on a plan, the gallery which is supposed to show all tasks for that plan (using the ListTasksV3 function) shows an error that says "You do not have the required permission to access this item". Clearly, the user has the required permissions if the user was allowed to access the group and the plans within the group, why is access being denied for the tasks within a plan? I looked around and it appears that Planner doesn't even have the functionality to limit task access based on user, so I'm not sure what's happening. As a side note, I originally implemented this with the depreciated ListTasksV2 function which lists all tasks for a plan and doesn't take a groupID as a parameter, and this worked fine (at least for accessing the tasks. There were other issues that I assume are related to its depreciation, hence the switch to the active function ListTasksV3).
