Taiwan has banned most non-citizen arrivals since early 2020 but has recently allowed business travelers to enter with a quarantine.
There have been talks that the country would reopen for select international arrivals without quarantine from July (read more here). Still, Taiwan has now extended the international transit passenger ban through September 30, 2022.

Conclusion
When I was looking and booking flights for my current trip in intra-Asia, United and Air Canada often offered flights with long connections in Taipei that I thought were not feasible.
Not sure what happened to Taiwan’s approach to Covid-19 was very reasonable at first. Keeping the country closed and banning transit passengers does nothing to the infection numbers now.
Let’s hope that they quickly relax entry requirements, although it appears unlikely that they would not require shortened quarantine at first. In the meantime, I would be very hesitant to purchase any travel that involves transiting in Taiwan.
