Yes. No idea what is going on. :-(
My cable box just started getting a similar error "ACT3"
what kind of cable box do you have..mine is DCX3600-M
Just a guess, but it sounds like these cable boxes were receiving an update from Spectrum's servers, perhaps a firmware update or other major software release. Are you saying that the box is stuck on this status? For how long?
You may be able to reinitiate the sync by unplugging the box for a minute or so then reconnecting the power to let it go through the process again.
