Hi @Anonymous,
Anyone else faced to the same problem below ?
Seems like there is a problem currently with the PowerApps engine for customized SharePoint forms. Not only the page that shows history versions for a form is broken (see first capture below), but the forms themselves are broken (all datacards are misplaced and the form won't run in SharePoint anymore) and whatever version I try to recover, the form stays broken (see second capture).
This started just a couple of hours ago... And I've made some tests on differents tenants with the same result.

Here is my form that is broken now:

The forms don't load anymore:

The tenants are located in Europe (I don't know if this is relevant)...
Would anyone have inputs about a possible issue at the moment with the PowerApps engine ?
