Power Apps doesn't work from SP Customized form

[Anonymous]

Hi, There

The Power Apps form does not load when I click the New button in SharePoint.

Is there problem with Power Apps?

Same for me, it takes 10 min to load each form , whats wrong?

We have the same issue. Some forms which were not modified in the last weeks are loading very slow (>3 min at least). Our datacenter region is Europe West. This occurs in all browsers (Firefox, Edge, Internet Explorer)

Same here. We just see: "getting your data"

Same here, ALL my customised forms are not working today and either say Getting your data when editing a Sharepoint list item, or for a new one the spinner just keeps going. Very annoying on a day we had a new IT support ticketing system using customized forms going live.
