Yammer connected Office 365 groups include a Plan. I have started using the plan in a Yammer group to coordinate writing blog posts with other authors. Initially, the plan was not visible in the Planner mobile app. But after a few days, the group name and plan appeared in the Planner Hub. I could access the plan via the browser and mobile app.
I checked the Planner app today and the plan is missing from the hub. Here today, gone tomorrow.
Does anyone else in this community use a Yammer connected Planner with the Planner mobile app? Or do experience the same problem I do?
