Most SMS with login codes not forwarding to Mac?

Running iOS 13 on iPhone XS and Mojave on new MBP15.


Several texts with login codes such as notably from Twitter show up on my Phone but not on my Mac messages and thus not autofilled in safari which is a feature I've loved.


Looks like some SMS with codes do forward such as Google and Facebook. But twitter and some others consistently do not it seems on iOS 13. Anyone else seen this issue or know of a workaround?
