If I include a PCF on a Canvas App, the only way I can get the updated version of the PCF in the Canvas App is:
- open the Canvas App for edit
- then I get the message dialog telling that that the component is not up to date
- if I choose to update the component in the app I always get an error (screenshot attached), so I need to use the "skip" button
- then I need to delete the component from the Canvas, save and close the app, open again and import the PCF in the app, configure again.
I know is still in preview, but I just wanted to get sure that this bug is known. (or maybe there is a workaround I'm not aware about)
Just in case it helps, I did increment the manifest and I use an unmanaged solution.

Kind regards,
Diana
