Error reading Excel file from Powerapps

Hi guys,


Hope you can help with the following issue.


I have a PowerApps based on Excel Online file. Everything was going Ok but since a few days ago I'm getting this error when I open my app "not a legal oleaut date"


Any idea about this? I'm sure that everything on date fields on the excel are actually date and I tried to reload the file to OneDrive and then refreshing the PowerApps Connection but nothing

  1. Clear Cookies and Cache, and retry
  2. Remove and re-add the data source from PowerApps, then retry #1, then retry it.
    1. Also, after doing this, try clicking the refresh icon a few times in PowerApps Maker as well.
  3. Remove the Excel Online connection, and then if needed recreate the Connection by removing the connection under -> Data -> Connections -> Find Excel Online Connection -> Use Ellipses ->  Remove Excel Online Connection., then retry #2, then retry #1, then retry it.
