Hello, I see many messages in this forum with topic "Connection not configured for this service' but no one is related exactly to my problem.
From my PowerApps aplication is running the Flow (with PowerApp trigger), it works fine when I tested it as owner in develop environment. Then I shared the app for test accont user. When test user launch the app with included Run Flow action, this message appeared: Error: Connection not configured for this service.
About the Flow: most actions are working with Sharepoint lists
Test user account has permission for all Sharepoint lists.
I deleted and re-created all connector for test user account / didnt help.
I use many other simillar Flows but only one of them has these problem.
