Hello,
I have a custom form in SharePoint built with PowerApps. The initial page has just one dropdown. Based on the values of this dropdown rest of the fields are un-hidden (on the same screen).
When "New" is clicked on the SharePoint to make a new entry, the 5 little dots keeps rolling and it doesn't let me choose from the dropdown, I have to refresh the browser several times and try my luck.
When I go to PowerApps editor (by clicking Customize with Power apps) the app works perfectly fine there, there is no delay in the app.

Seems like there is an issue with SharePoint talking to the Power Apps but I am not sure.
