Microsoft Power Apps & Flow Limitation - August 2019

So, I was working on Power Apps & Flow and facing some weird limitations. So I am witting a blog in case I or any one of you got a client that comes with these limitation, you can provide these reference link and ask them to do raise a ticket with Microsoft.


  1. Power Apps Forms - Attachment Control File upload size limit to 10 MB.

    Though SharePoint allows you to upload 250 MB file per attachment, Power App will only allow you to upload 10 MB file. Recently we got news that the hardcore limit will be increase to 100 MB.  And it will be available by September 2019.
    Update - then have again moved the deadline back and is not available till next year.

  2.  Flow time out on Approval action

    Flow provides you OOTB Approval action. You can set timeout period up to 30 days. After that flow will timeout. But when you run the flow it may show you error "your flow time out" if you keep it open to see the stage (after 10 to 15 minutes). But if you go back to list and click on running process again it shows it is running. This is somewhat confusing for end users.

  3. Flow Approval action - assigned to change
    If approver is not available, we are not able to delegate approval to someone else. In that case approval will timeout and flow ends. We can use patch mentioned in below link for work around for this now:

  4. Flow Approval Action - Markdown language - support for outlook client
    The approval action mail body can be only accept makdown language. This is very time consuming in terms of setting up proper formatting if you do not have practice of markdown language. Also the language has many limitation compare to html formatting. And outlook client is not supporting it. 
I will keep on adding bugs that I am facing. Also I will try to add new post if Microsoft release any update on above issues.
