I'm trying to test the data integrator. I've setup a demo d365 CE environment, I've created connections in the PowerApps environment, I've created a connection set in the Power Platform admin center.
When I try and create a project it asks to 'choose template', it then says there is nothing to display.
Screen shots attached.
I've never tried the templates, but I usually create my Data Integration aka Dataflows via make.powerapps.com --> Data --> Dataflows. Suggest to try it from there to see if you can create your Dataflows with the desired connectors/data sources.
