I'm facing issues upgrading to Radzen.Blazor 5.0+ and encountering the typical visual problems reported by other users. However, my case is slightly different: we load the styles not in the App.razor file but in the \_Host.cshtml file. This setup is making the update particularly challenging. Does anyone have advice or a solution for upgrading in this scenario? Thanks!
