I have created a feature layer from an Excel spreadsheet. I spent a lot of time adding multiple attachments (photos) to each point in the layer after it was created. I then made a Web Map and Instant App using the layer. This worked fine for several weeks. I need to update the layer now, but I am unable to do so because I keep getting the message, "There was an error publishing the service." when I click on the feature layer in my Contents area. I am unable to access any settings for the layer. I have tried deleting the layer from the Web Map, but I still get the error message. I am able to add it back to the Web Map with no problem, and the data is all still visible in the Web Map; I just can't access the feature layer itself in order to edit it. This is the second time I have had this same issue. I cannot afford the time involved to recreate the layer a third time.
My question is: is there a known issue that would cause a hosted feature layer to cease being editable after either a certain length of time, or a certain number of interactions with the layer (number of views or clicks on the popups?) Why can't I go back in and edit this layer, when I've been able to before? I don't believe it's anything to do with the size of the layer (size or number of photos) because it has been working and the file size has not changed.
