CRDTs mostly have a time notions like Lamport clocks, vector clocks, ... not actual device time => see more here: https://adamwulf.me/2021/05/distributed-clocks-and-crdts/

All of which have their own weaknesses. And all of them can suffer the split brain scenario.

And all but the last one fundamentally have lots of edge cases with e.g. high-latency sync

CRDTs are not a solved problem as of today, there is no perfect solution in the current state-of-the-art, it's still a field with quite some active research.
