According to this article reciting parashat hatamid is considered a chiuv deoraita (biblical obligation) at least by Rabbeinu Yonah ( more than can be said about most other parts of davening). Yet in my experience, most nusach Ashkenaz synagogues outside of Israel completely skip that section. They begin with birkot hashachar, continue with le'olam yhei adam and shma', and then after the berakha of mikadeish et shimcha barabim they skip a bunch of pages straight to Rabbi Yishmael omer.
What is the reason that many shuls skip over this section and how do they justify skipping a section that (at least according to one opinion) is more important than most of the other parts of davening that they actually do say?
The reason I am focusing on nusach Ashkenaz synagogues outside of Israel is because in my experience Sephardi synagogues do say the korbanot and in Israel most Ashkenazi synagogues start with Rabbi Yishmael omer (presumably people say korbanot before getting to shul). My question is not meant to be limited to Ashkenaz shuls in chu"l.
