Yes, we are in agreement. The almanac data provides a coarse spacecraft position, while the ephemeris data is finer and includes clock corrections.

Since the telemetry is embedded in the carriers, and I am receiving telemetry fine, this means that the spacecraft and payloads are working.

My bet is that they are needing to update new ephemeris data. Since the onboard oscillators take a long time to stabilize, my guess is that the clocks were reset or turned off for some reason and now need time to stabilize. Once stabilized, the new ephemeris data can be generated and uploaded to the payloads... in effect, a reboot of the constellation.

Then they will set the carrier flags to "usable".
