Hi,
i have a very big problem with Telerik Reporting after upgrading from version 2017 R3 (11.2.17.503) to the latest version.
I tested also the version (2018 R3, 2019 R1 SP1, 2019 R2 SP1).
After installing the newer version, customers see data of other customers!!
I have a multi-tenant system. All of our report data sources filters by the logged in user TenantId (ASP.NET Identity).
But with newer versions if a second user opens the same report, he gets the data from the first user.
You can find a working repro here: https://github.com/IT-CASADO/Telerik-Reporting-Bug1
Clone the project and bring it to run. In branch "master" you find the working version, and in the branch "features/v13.2.19.918" you find the broken version.
Regards,
Daniel
