This ODK-X pre-release should resolve the ODK-X Services server authentication issue with Android 9. Since the authentication issue was a blocking problem for some users, we are posting preview versions of ODK-X Services, ODK-X Survey, and ODK-X Tables.
Please help us test and find other issues before the scheduled release of v2.1.5 the first week of October.
ODK-X Services v2.1.5 Pre-Release
