of course i did check date (+/- 1 day) for the first leg to ensure the connection time still makes sense.
nope, allowing leeway to that still cant force SUB-SIN-TPE-USA to show up.
it is clearly intentional that SUB-SIN-TPE-USA is forbidden (and DPS-SIN-TPE-USA likely has the same fate as well), while CGK-SIN-TPE-USA is allowed (for inexplicable reasons)
this has been replicated across several dates
you can use Oct 9 as example.
USA is any west coast city, but in this test case it is SEA, as availability to SFO/LAX is not as limited for the dates i check such that you have to resort to transiting via TPE
Additionally, you have way more *A options heading to SFO/LAX which interfere with results.
Ultimately if all things are equal, the choice of which west coast gateway shouldnt matter
