Hi @Cornan The Iowan
If you want to know what bugs are fixed for the SSRS version, you can check the release notes: https://learn.microsoft.com/en-us/sql/reporting-services/release-notes-reporting-services?view=sql-server-ver16.
Exporting reports to Excel also has some limitations, you can check this link: https://learn.microsoft.com/en-us/sql/reporting-services/report-builder/exporting-to-microsoft-excel-report-builder-and-ssrs?view=sql-server-ver16.
Best regards,
Aniya
