Action Button showing "Error loading control" in PowerApps Form Designer.

[bo-stig-christensen]

I have added latest PCF Controls managed solution to my Development environment and testing out the Action Button in particular.

Is there an issue with the PCF or some strange issue with PowerApps Form Designer that it shows up as "Error loading control"?

Top button is an old webresource that I am replacing with the Action Button PCF below.
The PCF doesn't render in the form designer. However, it does render fine in the app itself.

I'm aware of this issue.
Need to find out why

@MscrmTools : Okay, great, so it's a known issue :-)
I was wondering if it might be some sort of caching issue in Make, but looked more and more like something specific to the PCF.
