Bug with Forms & Preview Feature: Delayed Load



just noticed a problem with the delayed load preview feature which cost me hours of my time today.


I have a form which submits data to a sharepoint list, nothing special here - connection,data source and permissions are set correctly - in the powerapps "studio" everything is working well. However, if I load the app using the URL, the forms won't load displaying an "No data source provided" error.

After deactivating the preview feature everything works well again.

PowerApps 3.19044.13


Please have a look into this.

Re: Bug with Forms & Preview Feature: Delayed Load

Hi @Sevket ,

Could you show me more details about the problem, like a picture of the error message or the settings of the form?

I've made a similar test, but not met the problem like your description.

Please check these points:

1)Have you set the form to the right mode?

2)Does your browser meet the configuration requirements?

3)Have you allowed third-party cookies?

If this doesn't help, refresh the data source, try to recreate the form.

Re: Bug with Forms & Preview Feature: Delayed Load

Hey @v-yutliu-msft ,


thanks for your reply - I tried it with following Browsers:


Edge/Firefox/Chrome/Vivaldi; 3rd party cookies are allowed as well.

Defaultmode is set to mode: Formmode.New


Before deactivating the feature I also tried to recreate the form on a new screen, even a new app and it didn't work as well. Also I have some navigation elements placed on the screen which also didn't work (Navigate(xxxx)).
