OnChange property disappeared from components

Hi, I'm having some problems with the component made with PCF. As you can see below, the OnChange property is completely gone.



I'm using @RAWilson big calendar for canvas app atm, but the problem is present with all of my other components. OnChange can't be found anywhere. This only happen a few hour ago, the property was still there this morning, It seems likely to be a problem with new powerapps update.

Hope this can be resolved soon, thank you.

Do remember that PCF in Canvas Apps is still in preview and not intended for use in production yet!

This is a regression issue and is not intentional removal . We have identified the fix and working on the deployment for the same. 


Apologies for the inconvenience caused. Please reach out to me if there are any questions .

I'm having the same issue, when I import the PCF into my application, the OnChange field is present, but:
- it's actually only working in edit mode (using Alt + click, and Play), not when I publish the app

- when I close and re-open the app, the field is gone


I'm not sure when it stopped working though.

I noticed it after powerapps version 3.20103.28, so around Thursday last week.

We are experiencing the same issue in Version 3.20104.33.


Initial use of the PCF control in the app works perfectly. When the app is opened for a second time the OnChange action seems to broken whenever it is filled in. We always get the following error:


The formula is: Set(_varTest, ShapeDrawingBoard1.Output)

This clearly does not contain any operator and therefore the error seems invalid.

Same Issue, the onChange is missing
I have the same component in 2 different tenants and in one is missing and in the other is still present. No changes made lately. 
Both have the same version 3.20104.33

@HemantG - any update on this - it's causing some pain!
