I would love to see a trigger in Flow for when a Planner task changes from one bucket to another.
For automation, this is one of the things that deters wider adoption.
For Planner to more popular, the 1-hour+ delay for its changes to show up in OWA Calendar also is a big deterrent.
How can this idea still in new status? It is almost 2 years old.
Nothing happened meanwhile with Planner related triggers. This feature is still missing for several times
Google has just bought AppSheet, you should speed up.
