A few months back I created an ArcGIS Online Developer Account that I had been using without issues. Last month I exceeded the free 50 credits so have increased my subscription to 200 credits a month. Since doing this however I seem to have a problem in accessing existing hosted feature services that I had previously published and as well as any new hosted features services that I publish to my account.
The existing hosted feature services display on a map but when I access the attribute table I get an error saying "Accessing data failed" (see attached).
Any new hosted feature services that I publish to the account do not display when added to a map and again show the "Accessing data failed" error when accessing the attribute table.
Any ideas why this is happening?
