PowerApps customize form not loading

Hi Everyone!

I have created a form using PowerApps customize form feature. when I click New in the sharepoint list the form keeps loading but the content doesn't appear!



104 REPLIES 104

Is there a relationship on loading times and the amount of sharepoint fields? 


I have 310 fields which are all simple; text number and date.


Sometimes it loads fast and then sometimes its slow. Changing between screens are also slow.

I have a list that includes thousands of items, when opening an item to view/edit the form loads for ages! It is practically not usable at this speed. Is the Form loading speed related to list length??

@Anonymous, could you please provide a session id? You can alt+ right click on the form to fetch it.

Hi cherie, 

Thanks for your quick reply. 

  • Session ID: f7a342be-0098-43bc-b367-7aa97336d8bf
  • PowerApps 3.18122.16

Note that the same problem (view/edit item not loading) occurs in Chrome and Edge. 


Forms in IE are no longer loading at all as of yesterday - anyone having the same problem??

The error suggests a problem with the frame, perhaps the HTML frame used is no longer supported in IE 11.. any ideas anyone?



@Anonymous, I haven't seen that issue at all. What is the url if you click open this content in a new window? Can you please share that url with me?

Hi Cherie,

I found the problem:

When I go to it appears I was not authenticated. Going there authenticates me and subsequently the error no longer appears... bit strange. 


However the forms are still not loading properly..  at least the PowerApps form is now called and shows, but as said earlier gets stuck in loading mode for nearly all my forms and in all modes (new/edit/view)?

This is in IE? Could you alt + right click to give me the IE session id?

Not applicable

Hello, thanks again for your assistance. 

This is getting strange though, I cannot get a session ID in IE: 

Alt+Rightclick shows the small field saying 'Session details', but clicking on that briefly shows the error I screenshotted before, then just shows the loading form. Clicking Alt+Rightclick again does nothing.. 

@Anonymous would you be able to collect a fiddler trace for me?

Not applicable

Sorry unfortunately I cannot provide a fiddler trace (as it captures everything; security concerns etc).

I can say that the same experience occurs on multiple lists within IE, and for none can I get the session ID. 😞

Would it help to check the IDs from other browsers?
