Error: Cannot set properties of undefined (setting 'useDataSources')

[chiara_c]

Hi, I am getting this message "Cannot set properties of undefined (setting 'useDataSources')" in a number of web apps created with Experience Builder. Those apps were properly working until yesterday.

Maybe a temporary problem? Someone could help me?

Thanks,

I am experiencing the same issue with one of my Experiences. https://experience.arcgis.com/experience/ccd3382204364f3da259e089158d6803

I am currently chatting with ESRI Support. I will let you know if they have anything to say.

Thank you for posting this, we are also having issues.  I'm hoping that this isn't a week or couple day problem to fix because we're having to down public resources.
