RE: Form Load Issue in v9 on prem UCI
So, I created a fresh organization, created a UCI app with contact entity in it. It was working fine. But, when I select only the information form on app designer, publish the app, go to the app, open contact record, it gave me the option to select other forms as well. I think that is a mess up on Microsoft. So basically on my faulted app, I wouldn't know which form it was trying to open and failing.
At the end, I couldn't find what exactly caused the issue, but I removed all unmanaged forms from my environement, put all managed forms in a solution from fresh organization and imported that solution into my faulted organization. Everything works fine now.
