Previously customized DispForm.aspx and now PowerApps custom form doesn't load in view mode
Before I describe my issue, first I want to confess to not following best practices when I was less-experienced. In order to create a solution that displayed "related" documents (via a lookup column)...
Remove all the customization done in DispForm.aspx, such as Media webparts, external js. Only keep the default webpart which shows all the columns without any JS and Save the page. Next time when you will load the page, it will show the PowerApps form. Spent lot of hours myself to figuring this out. See if it works for you.
