Existing PowerApps app cannot connect to existing SharePoint data sources (lists)

[kjones]

I have an existing PowerApps app that we have been using for months.  I used the application yesterday (Saturday). Today (Sunday), I attempted, via the web studio, to update the application when I noticed that none of the data sources were connected (View->Data Source).  All were in a "not connected" state.  Trying a "refresh" did not correct.  

I see that my Microsoft Flow source is also not connected.

Help!  This production appliation is now down and unavailable for users.

Hi @kjones ,

Could you pleasetry to delete the connection and then connect it again?

add-manage-connections

Hope this could be helpful.

Best Regards.

Thank you for your response. I believe that this is correcting the situation.  I did not make this change earlier as I was concerned that my PowerApp form layouts and modifications might be affected.

Can you tell me WHY this is happening?  I've not altered the SharePoint list schemas and the application was accessing the SharePoint lists properly the day before without incident. 

In short, how can I know that this will not happen again?  this is a concern for anyone using PowerApps for a production use.

Many thanks again for y

Did you change your password, I had to share my password to get IT support and when they were complete I had to change it back. It disrupted all my flows and I had to reconnect my Sharepoint list.
