Edit mode - blank screens (screens gone?)

On Friday I was working on a canvas app. It's connected to Office365Users, a SharePoint list, and a SharePoint library. Nothing fancy. Everything was fine on Friday but today it won't render screens in edit mode. Starts out ok, as I click back and forth b/t screens, they go blank. The forms, galleries, and controls are all still there, just invisible. No white screen canvas, just grey with the message you see when you drop a new form on a screen, "Add an item from the insert tab...". Refreshed data connections. Rebooted. Tried going back to older versions. Same behavior. Anyone else experiencing weirdness today?


UPDATE: Hours later....still messed up. When I hit one bad screen, suddenly all other screens are broken. All screens now just GONE. Grey. Nothing is visible but I can click on forms, galleries, and controls, which are all still there. What on earth went wrong here??? FYI - IE or Chrome, makes no difference.

Had something similar previously, and I cleared the internet cache and it was fine... fingers crossed you're back up and running soon 😉

Make sure you have ResetForm() - EditForm() and NewForm() where needed.


I get going on making stuff look nice and forget those sometimes and it will work that first time but then not after that without those in there.

I ended up rebuilding the whole thing from scratch. I suspect that maybe a bad Patch formula caused the problem. But I'm not sure about that or why it would totally kill the app even after it was deleted.
