The somewhat longer answer is that the journal “Journal of Advanced Research in Applied Mechanics” was till this month listed in the “Accepted titles” list, see enclosed file September 2023 (added in December 2022). In the latest update November 2023, see enclosed file the title is added to the current list of "Scopus Sources". This explains why in the Scopus link https://www.scopus.com/sourceid/21101152132 details like “Scopus content coverage” etc. are missing: they are too new.
