Cookie McCray shares some updates:
Back in 2020, we announced the deprecation of Report Server features Pin to Power BI, Mobile Reports, and Mobile Report Publisher. These features will be removed from versions of SQL Server starting with SQL Server 2022 and will no longer be supported. Only the last three releases, SQL Server 2016, SQL Server 2017, and SQL Server 2019, will be supported in maintenance mode until EOL (End of Life) for existing customers.
There are some interesting things in here but nothing that makes me say Reporting Services has a real future.
