They must have fixed it because I drive my two main monitors from a dock connected to one port and then my 3rd monitor from the other port. Been set up this way for at least two years now.

I've been away for about 3 years now. My thunderbolt dock couldn't drive two monitors from my Macs, and I couldn't daisy chain display ports either. A Linux ThinkPad had no problem though. Glad they've finally fixed (implemented) it.

Note that modern Macbook Pros can drive crazy screens.

A Macbook Pro M4 or M5 drives TWO of these at once, well, for equivalent of quad 4K configured as dual super ultrawides:

PS. Use TB4 or TB5 dock from Cal-Digit (match the TB version of your mac), or this or one of the rebranded versions of the same OEM: https://www.owc.com/solutions/thunderbolt-dock, or an Ivanky Fusion dock if you want to go nuts with up to SIX displays, Quad 6K@60Hz and Dual 4K@60Hz:
