Hey, I found that there is one link broken on https://docs.opendatakit.org/odk-x/services-install/ . Link which is broken is OI File Manager “https://play.google.com/store/apps/details?id=org.openintents.filemanager”.
Best,

OI File Manager for ODK-X discusses this; since it has been down a while we may want to update the link to the github.
