Having just upgraded from PBIRS 2017 to Jan 2023 Build 15.0.1111.115,
I find that non-admin users get this error on the Home folder and other folders that contain .rsmobile reports:
"Could not load folder contents. Something went wrong. Please try again later."
With all due respect, this error is most unhelpful. Server logs suggest an authentication error but through must trial and eventually good fortune I discovered that the error only happens in folders that contain .rsmobile reports.
I know that .rsmobile report suport was removed in Sep 2022. (A premature removal since I can't practically pass =username() as a parameter to SQL Server in Direct Queries.)
So I knew I would have to delete the .rsmobile reports eventually, but would you believe it, as Admin, I click on the ellipsis on an .rsmobile report and I get this error: "An error has occurred. Something went wrong. Please try again later."
@Petebro I figured you'd want to be aware of this because I expect more upgraders will encouter it in future.
My options appear to be:
1) Downgrade the server: Impossible I believe.
2) Access the ReportServer/ReportServerTempDB databases and remove the reports through there. Wish me luck.
3) Using my PBIRS database backups from the earlier version*, restore them to an RS instance of an earlier version, delete the .rsmobile reports, then upgrade. *And loose my current work on new PBI Mobile reports.
If anyone has other ideas, I'm open.
PS: This is not simply a Manage Folder > Security issue.
