Beta 4 was installed with the Recommended set of resources (85 \ 2202 library resources). Then I thought to Scan the remainder of my resources from a backup, but the Indexer showed that a number of resources "failed to open at one or more locations; requiring discovery." These were not indexed, but were shown as "On Device".
5037.LogosIndexer.zip
After a restart, a download of 880 MB was available, and "On Device" had reduced from 2202 to 2065**. I re-scanned from a fresh backup but nothing was discovered/indexed. The 880 MB download didn't make any difference either.
The first log below shows the scan, but I'm not sure if the download of 880 MB is shown

** The137 resources removed from "On Device" status were all Temporary, but 12 temporary ones were indexed.
