I'm attempting to append some data (zipped geodatabase) to a hosted feature layer in ArcGIS online. The same process that I have been using for months never completes. I am able to pick the zipped geodatabase, specify that it is a geodatabase, it will analyze and ask me whether or not to "update existing features". When I click "Apply Updates" it looks like it is working but stays stuck on the loading page. I have a polygon and a point layer that I have been updating this way and it is no longer working for either.
Has anyone else experienced this issue?
