This is disappointing, but it parallels the limit on the M1 based Macbooks which only natively support one external display 🙁 I have tested this on my own M1 based machine and only one display works even if you use a Thunderbolt dock.
Some people add more monitors by using USB-C displaylink adapters/docks but hopefully Apple will remedy these issues when they release their “Pro” models with native external multi-monitor (dual, triple, quad) support. 🙂
