Generally, the new versions are also available from our authenticated NuGet feed online, but with trial licenses that have had a previous trial so soon, the system may cut off access as a general licensing behavior. We have taken extra steps to allow trials to be downloaded for Blazor in such short timeframes, considering it is a new and still experimental technology, but retrofitting that into the live feed could break something for the hundreds of other packages we have, and we have not taken this risk.
