Of course you’re right that it not only chassidim who follow this shita. All i was saying is generally, chasidim follow ‘2nd skiah’. Most non-chasidim among the ashkenazim, i.e. litvish and ‘yekkish’/yotzei ashkenaz are makpid to daven before first shkiah, like the mishna berura.
The original yekkish minhag is based on the maharil and others, which is older than the shulchan oruch and rema, and that doesnt actually mention shkia as a limit for davening mincha. This is why kehilos like Breuers and other yekishe kehilos daven after shkiah.
I’ve never been there for shabbos, but i doubt they are mekabel shabbos after 1st shkiah like some chasidish places do. Please could someone confirm this.
