Why window is not showing? Customize the main form lesson - Create a Microsoft Dataverse table

Instructions from "Microsoft doc" how to "Customize the main form" lesson "Create a Microsoft Dataverse table" in my case the main window does not appear (colored in red), maybe someone knows why this problem occurs? I use the Chrome browser, I use the development account Power Apps (for free). I am preparing for the Pl-100 and practicing as instructed. Learning is difficult for me because the system does not work smoothly with certain exercises.

Hi @GregJohn 


In your screenshot it looks like the window is still loading. What is your internet bandwidth like? Have you tried refreshing the browser and clearing the cache? Every now and then I will get a page that gets stuck and usually just refreshing the page does the trick.

Try forcing the browser to clear and reload the javascript cache <ctrl><f5>

Also could try Switch to Classic (on the command bar in your screen shot) to see if the form loads in the classic interface.

Hello HSheild,

the window is loading into infinity. It's just loading and nothing happend. Yes sure thank you for your advise,  I also tried refreshing the page (F5), closing the browser and reopening, clearing the cache. I tried to repeat the exercise with another user account, but the window does not open and it's loading into infinity.

Anyway It's working in a Classic Form, I will use this one in the future, hope will work smoothly with other exercises. Thank you for cooperation. 🙂
