All my apps were working fine up until this point. I created a new app, connected to a new excel file in my onedrive, and I get the same error.
I believe we made a change over the weekend that restricted unmanaged devices connecting to O365, but this is coming from device that are managed and on the network. (Conditional Access in Office 365 by selecting "Allow limited, web-only access" in the SharePoint Admin Center, under "Unmanaged devices")
(We were seeing this in Chrome as well, which required an add-in to fix)
Does this mean, with this setting turned on, we can't use onedrive anymore with powerapps?
Some other users in this Community have faced similar issue with you. The Product Team is investigating this issue, if this issue is fixed, I would reply here.
As an temporary solution, please consider turn off the "Enable enhanced Microsoft SQL Server connector" option, and turn on the "Formula-level error management" option within Advanced settings of App settings of your app, then re-publish your canvas app, check if the issue is fixed.
If the issue still exists, please consider remove the Excel table connection from your canvas app, then re-add a new connection to it with your proper credential from your canvas app, then re-publish it again, check if the issue is solved.
