OT: Sirius/XM Hijacked By BLM ??

Did any of you with SiriusXM experience being unable to receive your customary stations while driving ~ 3pm EDT ? I kept getting the "Acquiring Signal" display indefinitely (manual says should go away in 2 seconds if you see it.) I pulled into a lot to call Sirius XM to find out wtf was going on, automated voice said 29 minute wait for live rep. Meanwhile I manually tuned down from my favored Channel 6 to Chanel 0 for an alternative XM contact #, no help. During this process, I happen to pick up Channel 4, which is a Soul Hits kind of station, one that the BLM crowd would probably like. That was the only channel that I could get.Virtually any other station that I tried got the "AS" display. I ran my errand in store, and when nearly home, everything returned to normal.
Did anyone else have the same problem ? I can only guess that a BLM devotee somehow screwed with XM broadcast for a period of time, 15 minutes or more.
