Yes, we have had to reconnect the Uber app with Concur Expense. Users were no longer receiving Uber receipts in Concur, then realized the connection between the two was removed. Once the connection was reestablished they received Uber receipts in Concur again. Have you received any updates from Concur?
I have the same issue when I look at the connected app today. Uber is no longer connected. I wonder if this is the direct result of the upgrade.
