Cannot load progress bar during plioting on pavlovia

Hi, I try to use the progress bar (one kind of component in stimuli) in the psychopy and it works very well during my local debugging. But when I piloted my study online (pavlovia), it didn’t show any errors or bugs but the progress bar just disappeared, while the rest components worked.

Is this because the progress is still in the Beta version and cannot be applied in online experiments?

Psychopy version: 2023.2.3

Was your background white by any chance? at the moment I know that the fill of Progress bar doesn’t quite work online - meaning it is always white - so it could be invisible on a white background. To test try putting a dark poly gon larger than the progress bar behind it.
