Seems like you are using KoBoToolbox on your own server instead of one that is available publicly through OCHA server or HHI server. FYI please be informed that some features including the row level permissions (which are available on the OCHA server or the HHI server) are not updated and available on the server you are currently using (KoBoToolbox installed on your own server). KoBoToolbox will be releasing the updated version of the same soon where you shall be able to use the missing features that is not present which is present in OCHA and HHI server.
Don’t exactly know on when the next release will be out which should support the row level permissions. However, when released, it gets announced here in the community page. Hence, please keep visiting our page to get updated on the same.
