It seems like you have forgotten to update your Trial for Telerik Blazor. The latest version for that is still 2.30 which is a really old version, from 2019 I think, so people trying out that won't be close to the current version. Also if they buy a license without updating thinking they already have the latest version as they just installed it. It is listed as having been updated December 8 but I doubt that based on the version number. You might want to look into this.
