Hi I have created PowerApps forms for SharePoint that work great, but for one list it does not open the form, the new button and edit/display forms do not open. There is no loading onthe mouse or indication that the page is doing anything.
The only difference in the list is that it is created from an Excel sheet that I have used the export to SharePoint function. The list comes across great but I would like to customise the form to make it easier to use.
These are the steps I use to customise the app - so I know it is connected to the list
List settings -> form settings -> customise in PowerApps
I have tried recreating the list before formatting the columns, saving the list as a template and importing it from this template.
I get the same result, the new and edit buttons not opening any forms.
As a test I created a new List in SharePoint and connected the PowerApp up fine and the buttons work here, so I think i am doing the right steps it just doesnt seem to be working for lists imported from excel?
This list has ~ 600 items, is there another way of importing this data into a list than using the export to SharePoint function in excel?
