Power BI Report Server October 2020 update has been released.

Hi Anonymous , cm6431

Just wanted to provide an update on top of the message that Pete have above. Currently, we dot not have a repro for any issue reported after the update to october release, this makes it dificult for us to provide an updated version. In order to make progress we are looking for someone:

Who are running the updated october release (version 15.0.1104.264 published on 11/18/2020),
Have republished their report using enhanced metadata enabled after the updated version of PBIDesktop optimized for reportserver (version 2.86.1321.0 published on 11/18/2020),
Is willing to share the pbit of the report and relevant logs from the server.
So if you have a consistent issues and are willing to provide a repro, please reach out to Petebro or myself so we can investigate. We also understand that you might only have a repro using confidential data that can't be shared, in that case I suggest to contact your microsoft support contact who can help diagnose the problem and build a repro without sensistive data.

Also, for customers who have upgraded and are blocked with issues, I just want to call out the workaround. Before the file is upgrated to the new format, a backup copy is saved in the app data folder:

C:\Users\guboreki\AppData\Local\Microsoft\Power BI Desktop SSRS\TempSaves\Backups

And the "enhanced metadata option can be disabled under options/preview features in powerbi desktop". So in short, you can disable this option, restart powerbi desktop, reopen the backup and you should be able to use with the same format as it did in May 2020. But a word of warning is that the fallback option will be removed in the next release of report server, so we want to identify and fix any issues that we are having with enhanced metadata.

Thanks
