Hello Power Automate Community.
I want to ask for confirmation regarding the maximum number of Planner's tasks that can be read by Power Automate. So here's my case:
My company has been using Planner for quite a long time. Lately, we've reached around 800 tasks. With overwhelming number, I want to make a Power Automate flow that can read a task with specific criteria, then post it into the Microsoft Teams chat as a daily/weekly routine reminder for that specific criteria. The problem I found is only 400 earliest tasks are screened by the flow. So if I manually check from Planner, there are some older tasks which not included in the reminder. I also found that it even read the completed tasks, hence the process of screening the tasks may be deemed unnecessary from the flow itself.

Picture 1: The number of tasks in my company

Picture 2: My test run shows that only 400 tasks were filtered by the flow.
My question is:
1. Can Power Automate screen more than 400 tasks here? If it could, does that mean there's a problem with my flow, maybe because I accidentally set a limit?
2. Can we perform a filter directly from the Planner action? Similar to how SharePoint action works, I remember we can set a filter query. That way, I think it can limit the progress criteria easier.
