I am trying to add content to a folder in my ArcGIS online account, however it is not working.
The specific issue I have is during the upload stage, as the 'Creating Service' box on the left-hand side doesn't stop loading and the 'Open in Map Viewer' can't be clicked on. When I come out of that and go to content, I can see the file there, but when I click on them and go to 'Open in Map Viewer' (which is active), I get the message 'The layer, xyz, cannot be added to the map'.
I have tried trouble shooting (with ref to:
https://community.esri.com/t5/esri-technical-certification/troubleshooting-error-the-layer-layername-cannot-be-added-to-the/ba-p/885847) but nothing is working. On Monday I could add my zipped folders to ArcGIS online but today I can't. I've checked the folders contain all necessary files (8 in total (CPG/DBF/PRJ/SBN/SBX/SHP/SHP.XML/SHX) and same file types as previous folders that worked on Monday), the file sizes are no larger than usual, I've tried on Firefox and Chrome, on incognito browser to avoid caching issues, and on two laptops to make sure there aren't update issues interfering with uploads or anything. My internet speed is the same as usual so shouldn't be impacting upload speeds. I have also tried with other files from coursework that should work and these do not upload either, therefore I expect the issue is with ArcGIS online rather than my files.
Could someone please look into this file upload issue?
