It seems like my web maps and web apps are having issues with hosted feature services from AGOL.
Each time the web map is loaded, a different layer will give the error - <Layename> cannot be added to the map.
I also notice that some layers that successfully loaded on the webmap were returning error 400 when debugging the issue on the browser.
As most of our feature services are sitting on https://services1.arcgis.com, was wondering if anyone else is having the same issue.
AGOL Health dashboard reports that everything is fine.
Same problem that is affecting syncing on Collector Android - for publisher accounts. User accounts can still sync.
Not affecting Apple Collector Aurora syncing.
Also affects viewing feature layers on publisher accounts using ArcGIS On-line with Chrome. User accounts are OK.
The sync error on Android Collector says the publisher does not have permission to sync their own feature layer. Very odd but consistent with the Chrome permission issue.
Only partially fixed. User accounts can now sync Collector edits again, but the publisher of the feature layer is being denied permission to sync their own feature layer (when logged in with their publisher account). So I have to use someone else's account on my phone to use off-line Collector. Very odd.
