I utilized the Radzen progress bar here, but the two progress bar colors are not displayed in my UI.The ProgressBar is displayed in white.Could you kindly provide a remedy for the progressbar showing two colors? For 50%, the backdrop color is black.
What theme are you using? It looks as a CSS caching issue. If you upgraded from Radzen.Blazor 4.x to Radzen.Blazor 5.x recently check this thread: Upgrading to Radzen.Blazor v5.0
It is probably old. Reapply it again from Radzen Blazor Studio - change to a different theme and then back to fluent. Also try clearing your browser cache.
